Question

Explain replace(old, new [, max])

Answer 1

The replace() method returns a copy of the string where all occurrences of a substring is replaced with another substring.

Explanation:

Python's built-in string function replace() returns a copy of the string where old occurrences were replaced with new ones, potentially limiting the number of replacements to max.

• Syntax - str.replace(old, new[, max])
• Parameters

1. old − This is old string to be replaced.
2. new − This is new substring, replacing old substring.
3. max − If this optional argument max is given, only the occurrences of the first count shall be replaced.

• Return Value - This method returns a copy of the string replaced by new, with all occurrences of substring old. If the optional argument max is given, only the occurrences of the first count are substituted.

Answer 2

The replace method is used in Python to replace the occurrence of old with new in a string in which we set the maximum condition.

Explanation:

#!/usr/bin/python

str = "my name is pisti.pisti is really fit and fine”

print str.replace("is", "nas")

print str.replace("is", "nas", 4)

• In the above example, old=is, new=nas and max is optional. Then the output of the above program would be  

        My name nas pnasti.pnasti nas really fit and fine.

• In the above example, old=is, new=nas and max=2. Then the output of the above program would be

         My name nas pnasti.pisti is really fit and fine.
