Python convert list of strings to list of integers

# Basic syntax:
list_of_ints = [int(i) for i in list_of_strings]

# Example usage with list comprehension:
list_of_strings = ['2', '3', '47']
list_of_ints = [int(i) for i in list_of_strings]
print(list_of_ints)
--> [2, 3, 47]

Change string list to int list python

Use the map function (in Python 2.x):
results = map(int, results)

In Python 3, you will need to convert the result from map to a list:
results = list(map(int, results))

Python convert list of lists of strings to int

# 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]]

# Note, if the strings don't have decimals, you can omit float()
