Using the map() function you can convert a list of strings into a list of int (number). Use the map() function in Python to apply a function (in this case, int()) to every element in a list, and get back a new list with the modified values.
Python map string to int example
A simple example code converts the list to an integer list using the map function.
T1 = ['13', '17', '18', '21', '32']
res = list(map(int, T1))
print(res)Output:
Another example
# Define a list of strings
num_strings = ['10', '20', '30', '40', '50']
# Use map() to convert the strings to integers
num_ints = list(map(int, num_strings))
# Print the resulting list of integers
print(num_ints)
In this example, we define a list of strings called num_strings. We then use the map() function to apply the int() function to each element in the list. The resulting map object is then converted to a list using the list() function, and assigned to the variable num_ints.
