How to use string.replace() in python 3.x

Question

The string.replace() is deprecated on python 3.x. What is the new way of doing this?

Answer 1

The replace() method in python 3 is used simply by:

a = "This is the island of istanbul"
print (a.replace("is" , "was" , 3))

#3 is the maximum replacement that can be done in the string#

>>> Thwas was the wasland of istanbul

# Last substring 'is' in istanbul is not replaced by was because maximum of 3 has already been reached
