How to pad with n characters in Python

Question

I should define a function pad_with_n_chars(s, n, c) that takes a string \'s\', an integer \'n\', and a character \'c\' and returns a string consisting of \'s\'

Answer 1

well, since this is a homework question, you probably won't understand what's going on if you use the "batteries" that are included.

def pad_with_n_chars(s, n, c):
    r=n - len(s)
    if r%2==0:
       pad=r/2*c
       return pad + s + pad
    else:
       print "what to do if odd ? "
       #return 1
print pad_with_n_chars("doggy",9,"y")

Alternatively, when you are not schooling anymore.

>>> "dog".center(5,"x")
'xdogx'
