Python | Convert list of string into sorted list of integer
Given a list of string, write a Python program to convert it into sorted list of integer.
Examples:
Input: ['21', '1', '131', '12', '15'] Output: [1, 12, 15, 21, 131] Input: ['11', '1', '58', '15', '0'] Output: [0, 1, 11, 15, 58]
Let’s discuss different methods we can achieve this task.
Method #1: Using map and sorted()
# Python code to convert list of # string into sorted list of integer # List initialization list_string = ['21', '1', '131', '12', '15'] # mapping list_map = map(int, list_string) # sorting list list_sorted = sorted(list_map) # Printing sorted list of integers print(list_sorted) |

Output:
[1, 12, 15, 21, 131]
Method #2: Using list comprehension
# Python code to convert list of # string into sorted list of integer # List initialization list_string = ['11', '1', '58', '15', '0'] # Using list comprehension output = [int(x) for x in list_string] # using sort function output.sort() # Printing output print(output) |

filter_none
Output:
[0, 1, 11, 15, 58]
Method #3: Using iteration
# Python code to convert list of # string into sorted list of integer # List initialization list_string = ['11', '1', '58', '15', '0'] # using iteration and sorted() list_sorted = sorted(int(x) for x in list_string) # printing output print(list_sorted) |

filter_none
Output:
[0, 1, 11, 15, 58]
