File Sorting in Python

Question

I would like to sort a file in Python based on numerical values:

My input file looks like this:

66135 - A
65117 - B
63301 - C
63793 - D

Answer 1

you can try this way

with open('filename','r') as file:
    # spilt() the line with '-'
    lis=[line.strip().split('-') for line in file]
    # sort the lis using the values
    print sorted(lis,key=lambda x:int(x[0].strip()))
