Python String replace() Method
The method replace() returns a copy of the string in which the occurrences of old have been replaced with new, optionally restricting the number of replacements to max.
Following is the syntax for replace() method
str.replace(old, new[, max])
old -- This is old substring to be replaced.
new -- This is new substring which would replace old substring.
max -- If this optional argument max is given, only the first count occurrences are replaced.
This method returns a copy of the string with all occurrences of substring old replaced by new. If the optional argument max is given, only the first count occurrences are replaced.
The following example shows the usage of replace() method.
#!/usr/bin/python str = "this is string example....wow!!! this is really string"; print str.replace("is", "was"); print str.replace("is", "was", 3);
Let us compile and run the above program, this will produce the following result:
thwas was string example....wow!!! thwas was really string thwas was string example....wow!!! thwas is really string
