# <h1>Extracting and Visualizing Stock Data</h1>
# <h2>Description</h2>
# 

# Extracting essential data from a dataset and displaying it is a necessary part of data science; therefore individuals can make correct decisions based on the data. In this assignment, you will extract some stock data, you will then display this data in a graph.

# In Python, you can ignore warnings using the warnings module. You can use the filterwarnings function to filter or ignore specific warning messages or categories.
# 

# In[99]:


import warnings
# Ignore all warnings
warnings.filterwarnings("ignore", category=FutureWarning)


# ## Define Graphing Function
# 

# In this section, we define the function `make_graph`. You don't have to know how the function works, you should only care about the inputs. It takes a dataframe with stock data (dataframe must contain Date and Close columns), a dataframe with revenue data (dataframe must contain Date and Revenue columns), and the name of the stock.
# 

# In[100]:


def make_graph(stock_data, revenue_data, stock):
    fig = make_subplots(rows=2, cols=1, shared_xaxes=True, subplot_titles=("Historical Share Price", "Historical Revenue"), vertical_spacing = .3)
    stock_data_specific = stock_data[stock_data.Date <= '2021--06-14']
    revenue_data_specific = revenue_data[revenue_data.Date <= '2021-04-30']
    fig.add_trace(go.Scatter(x=pd.to_datetime(stock_data_specific.Date, infer_datetime_format=True), y=stock_data_specific.Close.astype("float"), name="Share Price"), row=1, col=1)
    fig.add_trace(go.Scatter(x=pd.to_datetime(revenue_data_specific.Date, infer_datetime_format=True), y=revenue_data_specific.Revenue.astype("float"), name="Revenue"), row=2, col=1)
    fig.update_xaxes(title_text="Date", row=1, col=1)
    fig.update_xaxes(title_text="Date", row=2, col=1)
    fig.update_yaxes(title_text="Price ($US)", row=1, col=1)
    fig.update_yaxes(title_text="Revenue ($US Millions)", row=2, col=1)
    fig.update_layout(showlegend=False,
    height=900,
    title=stock,
    xaxis_rangeslider_visible=True)
    fig.show()


# ## Question 1: Use yfinance to Extract Stock Data
# 

# Using the `Ticker` function enter the ticker symbol of the stock we want to extract data on to create a ticker object. The stock is Tesla and its ticker symbol is `TSLA`.
# 

# In[101]:


tesla = yf.Ticker("TSLA")


# Using the ticker object and the function `history` extract stock information and save it in a dataframe named `tesla_data`. Set the `period` parameter to `max` so we get information for the maximum amount of time.
# 

# In[102]:


tesla_data = tesla.history(period="max")


# **Reset the index** using the `reset_index(inplace=True)` function on the tesla_data DataFrame and display the first five rows of the `tesla_data` dataframe using the `head` function. Take a screenshot of the results and code from the beginning of Question 1 to the results below.
# 

# In[89]:


tesla_data.reset_index(inplace=True)
tesla_data.head(5)


# ## Question 2: Use Webscraping to Extract Tesla Revenue Data
# 

# Use the `requests` library to download the webpage https://cf-courses-data.s3.us.cloud-object-storage.appdomain.cloud/IBMDeveloperSkillsNetwork-PY0220EN-SkillsNetwork/labs/project/revenue.htm Save the text of the response as a variable named `html_data`.
# 

# In[90]:


url = "https://cf-courses-data.s3.us.cloud-object-storage.appdomain.cloud/IBMDeveloperSkillsNetwork-PY0220EN-SkillsNetwork/labs/project/revenue.htm"
html_data = requests.get(url).text


# Parse the html data using `beautiful_soup`.
# 

# In[91]:


soup = BeautifulSoup(html_data, 'html5lib')


# Using `BeautifulSoup` or the `read_html` function extract the table with `Tesla Revenue` and store it into a dataframe named `tesla_revenue`. The dataframe should have columns `Date` and `Revenue`.
# 

# <details><summary>Click here if you need help locating the table</summary>
# 
# ```
#     
# Below is the code to isolate the table, you will now need to loop through the rows and columns like in the previous lab
#     
# soup.find_all("tbody")[1]
#     
# If you want to use the read_html function the table is located at index 1
# 
# We are focusing on quarterly revenue in the lab.
# ```
# 
# </details>
# 

# In[93]:


tesla_revenue = pd.read_html(str(soup)
tesla_revenue = tesla_revenue[1]
tesla_revenue = tesla_revenue.rename(columns= {"Tesla Quarterly Revenue (Millions of US $)": "Date",
                    "Tesla Quarterly Revenue (Millions of US $).1":"Revenue"})


# Execute the following line to remove the comma and dollar sign from the `Revenue` column. 
# 

# In[94]:


tesla_revenue["Revenue"] = tesla_revenue['Revenue'].str.replace(',|\$',"")


# Execute the following lines to remove an null or empty strings in the Revenue column.
# 

# In[95]:


tesla_revenue.dropna(inplace=True)

tesla_revenue = tesla_revenue[tesla_revenue['Revenue'] != ""]


# Display the last 5 row of the `tesla_revenue` dataframe using the `tail` function. Take a screenshot of the results.
# 

# In[96]:


tesla_revenue.tail(5)


# ## Question 3: Use yfinance to Extract Stock Data
# 

# Using the `Ticker` function enter the ticker symbol of the stock we want to extract data on to create a ticker object. The stock is GameStop and its ticker symbol is `GME`.
# 

# In[55]:


gamestop = yf.Ticker("GME")


# Using the ticker object and the function `history` extract stock information and save it in a dataframe named `gme_data`. Set the `period` parameter to `max` so we get information for the maximum amount of time.
# 

# In[56]:


gme_data = gamestop.history(period ="max")


# **Reset the index** using the `reset_index(inplace=True)` function on the gme_data DataFrame and display the first five rows of the `gme_data` dataframe using the `head` function. Take a screenshot of the results and code from the beginning of Question 3 to the results below.
# 

# In[57]:


gme_data.reset_index(inplace=True)
gme_data.head(5)


# ## Question 4: Use Webscraping to Extract GME Revenue Data
# 

# Use the `requests` library to download the webpage https://cf-courses-data.s3.us.cloud-object-storage.appdomain.cloud/IBMDeveloperSkillsNetwork-PY0220EN-SkillsNetwork/labs/project/stock.html. Save the text of the response as a variable named `html_data`.
# 

# In[80]:


url = "https://cf-courses-data.s3.us.cloud-object-storage.appdomain.cloud/IBMDeveloperSkillsNetwork-PY0220EN-SkillsNetwork/labs/project/stock.html"
html_data = requests.get(url).text


# Parse the html data using `beautiful_soup`.
# 

# In[81]:


soup = BeautifulSoup(html_data, "html5lib")


# Using `BeautifulSoup` or the `read_html` function extract the table with `GameStop Revenue` and store it into a dataframe named `gme_revenue`. The dataframe should have columns `Date` and `Revenue`. Make sure the comma and dollar sign is removed from the `Revenue` column using a method similar to what you did in Question 2.
# 

# <details><summary>Click here if you need help locating the table</summary>
# 
# ```
#     
# Below is the code to isolate the table, you will now need to loop through the rows and columns like in the previous lab
#     
# soup.find_all("tbody")[1]
#     
# If you want to use the read_html function the table is located at index 1
# 
# 
# ```
# 
# </details>
# 

# In[82]:


gme_revenue = pd.read_html(str(soup))
gme_revenue = gme_revenue[1]
gme_revenue = gme_revenue.rename(columns={"GameStop Quarterly Revenue (Millions of US $)":"Date",
                                   "GameStop Quarterly Revenue (Millions of US $).1":"Revenue"})

gme_revenue['Revenue'] = gme_revenue['Revenue'].str.replace(",|\$", "") #Remove symbols


# Remove an null or empty strings in the Revenue column.

# In[83]:


gme_revenue.dropna(inplace=True)

gme_revenue = gme_revenue[gme_revenue['Revenue'] != ""]


# Display the last five rows of the `gme_revenue` dataframe using the `tail` function. Take a screenshot of the results.
# 

# In[84]:


gme_revenue.tail(5)


# ## Question 5: Plot Tesla Stock Graph
# 

# Use the `make_graph` function to graph the Tesla Stock Data, also provide a title for the graph. The structure to call the `make_graph` function is `make_graph(tesla_data, tesla_revenue, 'Tesla')`. Note the graph will only show data upto June 2021.
# 

# In[97]:


make_graph(tesla_data, tesla_revenue, 'Tesla')


# ## Question 6: Plot GameStop Stock Graph
# 

# Use the `make_graph` function to graph the GameStop Stock Data, also provide a title for the graph. The structure to call the `make_graph` function is `make_graph(gme_data, gme_revenue, 'GameStop')`. Note the graph will only show data upto June 2021.
# 

# In[103]:


make_graph(gme_data, gme_revenue, 'GameStop')
