The string method maketrans() in Python returns a mapping table for translation purposes which is usable for the translate() method in Python string. In simpler terms, the maketrans() method refers to a static method that creates a one-to-one mapping of a character in the into a string to its translation/replacement at the same position in the outta string. It is responsible for creating a Unicode representation of every character for translation.
Note - Both in tab and outta are required to have a similar length.
Following is the syntax for maketrans() method:
This method in Python string returns a translate table which is to be used translate() function.
The example below shows the usage of maketrans() method in Python String. Under this, every vowel within a string gets replaced by its vowel position -
#!/usr/bin/python from string import maketrans # Required to call maketrans function. intab = "aeiou" outtab = "12345" trantab = maketrans(intab, outtab) str = "this is string example....wow!!!" print str.translate(trantab)
When we run the above program, it produces the following result:
th3s 3s str3ng 2x1mpl2....w4w!!!
