Watch: Season 7, Episode 24 Seinfeld

In season 7, episode 24 of Seinfeld, Kramer visits a bank that promises to give $100 to anyone who isn’t greeted with a “hello.” Kramer is instead greeted with a “hey,” which he insists isn’t a “hello,” and so he asks for $100. The bank’s manager proposes a compromise: “You got a greeting that starts with an ‘h,’ how does $20 sound?” Kramer accepts.

In a file called bank.py, implement a program that prompts the user for a greeting. If the greeting starts with “hello”, output $0. If the greeting starts with an “h” (but not “hello”), output $20. Otherwise, output $100. Ignore any leading whitespace in the user’s greeting, and treat the user’s greeting case-insensitively.

Hints
  • Recall that a str comes with quite a few methods, per https://docs.python.org/3/library/stdtypes.html#string-methods.
  • Be sure to give $0 not only for “hello” but also “hello there”, “hello, Newman”, and the like.

Before You Begin

From the root of your repository execute cd conditionals So your current working directory is ... 

/conditionals $:
Next execute 
code bank.py
to make a file called bank.py where you’ll write your program.

Success

Your program must have a function call greeting that takes a string as an argument and returns an integer. Your main function must call this function and print the result.

How to Test

Here’s how to test your code manually. At the bank/ $ prompt in your terminal:

Run your program with python bank.py. Type Hello and press Enter. Your program should output: 

$0
Run your program with python bank.py. Type Hello, Newman and press Enter. Your program should output: 
$0
Run your program with python bank.py. Type How you doing? and press Enter. Your program should output: 
$20
Run your program with python bank.py. TypeWhat's happening? and press Enter. Your program should output: 
$100

Pytest

You can execute the below to check your code using pytest from the root directory.

pytest .\tests\conditionals\test_bank.py

A green output from running the test means it was successful. A red output means there is a bug in your code that you need to fix.

How to Submit

From github desktop or the command line, commit your changes and push them to your repository.

Codespace terminal or your local terminal.

Note

You will need to have installed git-scm for this to work locally

At the /datatypes $ prompt in your terminal: 

git add -A

git commit -m "your message here"
Commit all changes in the REPO with the comment “your message here“ note: If the file is not complete, adjust the comment to describes what is being committed

Note

Remember to replace "your message here" with a meaningful commit message that describes your changes.
