Python list rearrange the elements in a required order

Question

My main list has 44 names as elements. I want to rearrange them in a specific order. I am giving here an example. Note that elements in my actual list are some technical names. No way related to what I have given here.

main_list = ['one','two','five','six',.................'twentyone','three','four','seven','eight',.....,'fortyfour']

main_list = ['one','two','three','four','five','six','seven','eight'.................'twentyone',,.....,'fortyfour']

Answer 1

You can have a dictionary to use as your sorting key:

sort_keys = {
    'one': 1,
    'two': 2,
    'three': 3,
    'ten': 10,
    'twenty': 20,
}
main_list = ['twenty', 'one', 'three', 'ten', 'two']
main_list.sort(key=lambda i: sort_keys[i])
print(main_list)

Output:

['one', 'two', 'three', 'ten', 'twenty']
