Python: Sort list of strings by length

By supplying a custom function to the ‘key’ argument to the sort, sorted function, we can sort the data on multiple attributes.

 

Find the below examples.

 

Example 1: Using sort method.

countries1.sort(key=len)

 

Example 2: Using sorted method.

countryies2_by_length = sorted(countries2, key=len)

Find the below working application.

 

sort_list_of_strings_by_length.py

def print_list(my_list, msg):
    print(msg)
    for item in my_list:
        print(item)
    print()

countries1 = ['Albania', 'Canada', 'Australia', 'India', 'Chile', 'Bhutan']
countries2 = ['Albania', 'Canada', 'Australia', 'India', 'Chile', 'Bhutan']

countries1.sort(key=len)

countryies2_by_length = sorted(countries2, key=len)

print_list(countries1, "Sorted by length using sort method")
print_list(countryies2_by_length, "Sorted by length using sorted function")

Output

Sorted by length using sort method
India
Chile
Canada
Bhutan
Albania
Australia

Sorted by length using sorted function
India
Chile
Canada
Bhutan
Albania
