convert list of strings to ints python
# Python3 code to demonstrate
# converting list of strings to int
# using map()
# initializing list
test_list = ['1', '4', '3', '6', '7']
# Printing original list
print ("Original list is : " + str(test_list))
# using map() to
# perform conversion
test_list = list(map(int, test_list))
# Printing modified list
print ("Modified list is : " + str(test_list))
# Example usage using list comprehension:
# Say you have the following list of lists of strings and want integers
x = [['565.0', '575.0'], ['1215.0', '245.0'], ['1740.0', '245.0']]
list_of_integers = [[int(float(j)) for j in i] for i in x]
print(list_of_integers)
--> [[565, 575], [1215, 245], [1740, 245]]
