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

deletechars: list of characters to be removed from the source string.

This example 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);

This will produce following result:

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

#!/usr/bin/pythonfrom 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:
