How to Convert a List of Strings to a List of Integers in Python?

Converting Strings to Integers in a List

Question: How can we convert all strings in a list to integers?

Given: Consider a list like ['1', '2', '3'].

Answer: To achieve this conversion, we can utilize the following steps:

• Utilize the map() function to apply the int function to each element in the list.
• Convert the resulting object to a list using either the list() function or, in Python 2, simply use map() directly.

Example:

xs = ['1', '2', '3']
result = list(map(int, xs))  # Converts each string to an integer
print(result)  # Output: [1, 2, 3]

This approach efficiently converts all strings in the list to their corresponding integer representations, producing a new list of integers.
