Is it possible to do doctests in repl.it?

Question

I am using the website repl.it to code with python and I was wondering how I would use my doctests when using repl.it. Or any other alternative besides the classic print statement checks.

Answer 1

It can be done in the following way. If you execute the following code on repl.it it will give you the output shown below.

import doctest

def testing():
    doctest.run_docstring_examples(square,globals(),name="square")

def square(n):
    '''
    returns a square of n
    >>> square(3)
    9
    >>> square(1)
    1
    >>> square(6)
    36
    '''
    return n+n

testing()
name = 'Pete'
age = 35
num = 1

print(f'name is: {name} Age is: {age: ^10} num is: {num}')

Output:

The code is very trivial and once you understand it you can incorporate into your program. You may need to change the structure of your code to achieve this.
