Syntax

Following is the syntax for translate() method −

str.translate(table[, deletechars]);

Parameters

• table − You can use the maketrans() helper function in the string module to create a translation table.

• deletechars − The list of characters to be removed from the source string.

Example

The following example shows the usage of translate() method. Under this every vowel in a string is 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 above program, it produces following result −

th3s 3s str3ng 2x1mpl2....w4w!!!

Following is the example to delete 'x' and 'm' characters from the string −

#!/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, 'xm')

This will produce following result −

th3s 3s str3ng 21pl2....w4w!!!
