How to translate a python string according a given dictionary?

We can use the method translate() which returns a copy of the string in which all characters have been translated using table (constructed with the maketrans() function in the string module), optionally deleting all characters found in the string deletechars. 

 example

from string import maketrans   # Required to call maketrans function.
intab = "aeiou"
outtab = "12345"
trantab = maketrans(intab, outtab)
str = "This is a string example....wow!!!";
print str.translate(trantab)

Output

This will give us the output −
