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.
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.
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.

#1
tesla = yf.Ticker("TSLA")

#2
tesla_data = tesla.history(period="max")

#3
tesla_data.reset_index(inplace=True)
tesla_data.head()

Question 2: Use Webscraping to Extract Tesla Revenue Data

Use the requests library to download the webpage https://www.macrotrends.net/stocks/charts/TSLA/tesla/revenue. Save the text of the response as a variable named html_data.
Parse the html data using beautiful_soup.
Using beautiful soup extract the table with Tesla Quarterly Revenue and store it into a dataframe named tesla_revenue. The dataframe should have columns Date and Revenue. Make sure the comma and dollar sign is removed from the Revenue column.
Remove the rows in the dataframe that are empty strings or are NaN in the Revenue column. Print the entire tesla_revenue DataFrame to see if you have any.
Display the last 5 row of the tesla_revenue dataframe using the tail function.

#1
tesla_url = "https://www.macrotrends.net/stocks/charts/TSLA/tesla/revenue"
tesla_html_data = requests.get(tesla_url).text

#2
tesla_soup = BeautifulSoup(tesla_html_data, "html5lib")

#3
tesla_tables = tesla_soup.find_all('table')

for index,table in enumerate(tesla_tables):
    if ("Tesla Quarterly Revenue" in str(table)):
        tesla_table_index = index

tesla_revenue = pd.DataFrame(columns=["Date", "Revenue"])

for row in tesla_tables[tesla_table_index].tbody.find_all("tr"):
    col = row.find_all("td")
    if (col !=[]):
        date = col[0].text
        revenue = col[1].text.replace("$", "").replace(",", "")
        tesla_revenue = tesla_revenue.append({"Date" : date, "Revenue" : revenue}, ignore_index=True)

#4
tesla_revenue = tesla_revenue[tesla_revenue['Revenue'] != ""]
tesla_revenue

#5
tesla_revenue.tail()

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.
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.
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.

#1
gamestop = yf.Ticker("GME")

#2
gme_data = gamestop.history(period="max")

#3
gme_data.reset_index(inplace=True)
gme_data.head()

Question 4: Use Webscraping to Extract GME Revenue Data

Use the requests library to download the webpage https://www.macrotrends.net/stocks/charts/GME/gamestop/revenue. Save the text of the response as a variable named html_data.
Parse the html data using beautiful_soup.
Using beautiful soup extract the table with GameStop Quarterly 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.
Display the last five rows of the gme_revenue dataframe using the tail function.

#1
gme_url = "https://www.macrotrends.net/stocks/charts/GME/gamestop/revenue"
gme_html_data = requests.get(gme_url).text

#2
gme_soup = BeautifulSoup(gme_html_data, "html5lib")

#3
gme_tables = gme_soup.find_all('table')

for index,table in enumerate(gme_tables):
    if ("GameStop Quarterly Revenue" in str(table)):
        gme_table_index = index

gme_revenue = pd.DataFrame(columns=["Date", "Revenue"])

for row in gme_tables[gme_table_index].tbody.find_all("tr"):
    col = row.find_all("td")
    if (col !=[]):
        date = col[0].text
        revenue = col[1].text.replace("$", "").replace(",", "")
        gme_revenue = gme_revenue.append({"Date" : date, "Revenue" : revenue}, ignore_index=True)

#4
gme_revenue.tail()

Question 5: Plot Stock Graphs

Use the make_graph function to graph the Tesla Stock Data, also provide a title for the graph.
Use the make_graph function to graph the GameStop Stock Data, also provide a title for the graph.

#1
make_graph(tesla_data, tesla_revenue, 'Tesla')

#2
make_graph(gme_data, gme_revenue, 'GameStop')
