Which way would be more optimal in terms of performance, to make each element of the list a string?

Question

Python

Good afternoon, there is a list of 100 million numbers, which method will be more productive for further operations on the list (enumeration, sorting, etc.)?

l = [i for i in range(100000000)]
l = map(lambda i: str(i), l)
# Или
l = [i for i in range(100000000)]
l = [str(i) for i in l]
