How to Convert All Strings in a List to Integers in Python?
How can I convert all the strings in a list to integers in Python?
For example, given the list ['1', '2', '3'], I want to convert it to [1, 2, 3].
Can you show me how to convert list of strings to ints Python?
Hello All!
Well, while choosing an import style depends on your use case, let me share a quick tip for a common task in Python—how to convert a list of strings to ints in Python. Here’s an approach using a list comprehension:
str_list = ['1', '2', '3']
int_list = [int(x) for x in str_list]
print(int_list) # Output: [1, 2, 3]
This method is concise and ideal for most scenarios!
That’s a great example, @madhurima_sil!
Another way to convert a list of strings to ints in Python is by using the map() function:
str_list = ['1', '2', '3']
int_list = list(map(int, str_list))
print(int_list) # Output: [1, 2, 3]
This approach can be more readable in some cases, especially when dealing with functions that transform elements!
Both methods are excellent!
For those who prefer a more step-by-step approach, here’s how you can convert a list of strings to ints in Python using a for loop:
str_list = ['1', '2', '3']
int_list = []
for item in str_list:
int_list.append(int(item))
print(int_list) # Output: [1, 2, 3]
This approach is particularly useful if you want to add custom logic during the conversion process.
