expected two blank lines pep8 warning in python

Question

I\'m using vim editor as python IDE. Below is a simple python program to calculate square root of a number:

import cmath
def sqrt():
    try:
        num = i         


        

Answer 1

All answers seem to be correct. To avoid doing this by hand, you can also use the autopep8 package (pip install autopep8). The result of calling autopep8 filename.py is the same:

import cmath


def sqrt():
    try:
        num = int(input("Enter the number : "))
        if num >= 0:
            main(num)
        else:
            complex(num)
    except:
        print("OOPS..!!Something went wrong, try again")
        sqrt()
    return


def main(num):
    squareRoot = num**(1/2)
    print("The square Root of ", num, " is ", squareRoot)
    return


def complex(num):
    ans = cmath.sqrt(num)
    print("The Square root if ", num, " is ", ans)
    return


sqrt()

PS: have a look at if __name__ == "__main__":
