Write a Python program to calculate tax and tip. Ask the user for a check amount, and calculate the tax and tip, providing tip amounts for stingy, regular, and generous customers. Use the following steps:

Prompt the user for a check amount and store it in a variable called check_amount_str.
Convert check_amount_str to a floating point number and store it in a variable called check_amount.
Calculate tax amount (7%) and three tip amounts (10%, 15%, and 20%), storing each result in a separate variable.
Calculate total for regular customers including 7% tax and 15% tip. Print the results to the console like in the example below, including the base cost of the meal, tax, three tip levels, and total for regular customers.

The expected output from your program should look like the following:
Please enter check amount: $ 20
Base cost: $ 20.00
Tax (7 %): $ 1.40
Tip for stingy customers (10 %): $ 2.00
Tip for regular customers (15 %): $ 3.00
Tip for generous customers (20 %): $ 4.00
Total with tax and tip for regular customers: $ 24.40

Note: that it’s okay for now if you have more decimals, e.g. your total might look like $ 24.40000001. We will learn how to format your output later.
