Replacing instances of a character in a string

Question

This simple code that simply tries to replace semicolons (at i-specified postions) by colons does not work:

for i in range(0,len(line)):
     if (line[i]==\"         


        

Answer 1

If you are replacing by an index value specified in variable 'n', then try the below:

def missing_char(str, n):
 str=str.replace(str[n],":")
 return str
