Python find and replace in string based on a mapping dictionary [duplicate]

Question

I have a string

str = "abcdef"

and a mapping

map = {'a':'b','b':'c', 'c':'d'}

The expected output is

out_str = 'bcddef'

How can I apply mapping in one iteration in python?

Try:

s = "abcdef"
m = {"a": "b", "b": "c", "c": "d"}

print("".join(m.get(ch, ch) for ch in s))

Prints:

bcddef
