cleanest way to concatenate a single string to many other element contained in a list-CodePudding

What I have:

string = "string"
range_list = list(range(10))

What I want:

['string0',
 'string1',
 'string2',
 'string3',
 'string4',
 'string5',
 'string6',
 'string7',
 'string8',
 'string9']

What I usually do:

import pandas as pd
(string pd.Series(range_list).astype(str)).tolist()

What I would like to do:
obtain the same expected output from the same input, without importing libraries nor using loops

Since there is probably no way to do this complying my requests, any other solution cleaner and/or more performing than mine is well accepted. Thanks in advice.

CodePudding user response：

You can do this using list comprehension and f-string.

[f"{string}{idx}" for idx in range_list]

CodePudding user response：

This works too

string = "string"

str_list = [string   str(i) for i in range(10)]

CodePudding user response：

You can use map with a function or a lambda to avoid using a loop.

def get_string(x):
    return f'string{x}'

list(map(get_string, range(10)))

or with a lambda:

list(map(lambda x: f'string{x}', range(10)))
