My program:

def string_splosion(str):j=1c=len(str)i=0s=''while(i<c):s=s+(str[:i+j])i=i+1print sprint("Enter a string:")
s=raw_input()
string_splosion(s)Sample input:Code
Expected output:CCoCodCode
My output:
Enter a string:
code
c co cod code

Could anyone please explain me how to remove the space and get the expected output CCoCodCode for Python2.7.12

Thanks a lot!!!

Currently, you are printing each iteration separately. Though you can get your example to work by changing the logic a little bit, this is an easy job for Python magic:

>>> s = 'Code'
>>> ''.join(s[:i+1] for i in range(len(s)))
'CCoCodCode'
