Python: Fastest — Convert list of integers to comma separated string | by Akshay Chavan | Medium
July 27, 2020 - However, I had to find the fastest way to accomplish the task as I had to convert integer lists of length between 10000 and 12000, that too a multiple times. So, I decided to run some experiments. Here is the sample list to convert, with the 7 contenders and outputs: Except the last one, every other contender generates similar output. However, in a comma separated string, spaces after commas hardly makes a difference.

Use [str(i) for i in range(1, 71)]. This gives you the list of str(i) for all i in range(1, 71). The function str(i) returns i as a str value instead of as an int

Seems like you want something like this,
>>> l = []
>>> for i in range(1,71):
l.append(str(i))
>>> l

Depends on your result and description, I guess your code is something like:
b = """58738121385139B
9135A4251EF0
2B631B53C383"""
print(', '.join(b))
result:
5, 8, 7, 3, 8, 1, 2, 1, 3, 8, 5, 1, 3, 9, B,
, 9, 1, 3, 5, A, 4, 2, 5, 1, E, F, 0,
, 2, B, 6, 3, 1, B, 5, 3, C, 3, 8, 3
You should use split to achieve it
print(', '.join(b.split("\n")))
result:
58738121385139B, 9135A4251EF0, 2B631B53C383

Seems like your string consists of space-separated chunks of data, You could try this:

r/learnpython on Reddit: How to provide comma separated integer to a function as argument by user input
November 12, 2022 -
I ran into a problem of providing comma separated integer to function while practising variable argument
This is the function
def multiply_num(*numbers):
print(numbers)
product = 1
for num in numbers:
product = product * num
return productNormally I would provide the value while calling the function like this
print(multiply_num(3,7,9,2))
But I had problem providing such value through the input() command. After some tinkering this worked
num = list(map(int, input("Enter numbers: ").split(",")))
print(multiply_num(*num))Even though it worked, it kind of feels like a hack, is there a better method.

The input() function returns a string of the user input. Those comma separated values entered by the user are a one string. What you're calling a hack is actually the right way to convert that string to a list. You could use a list comprehension instead of the map function user_input = input('Enter numbers: ').split(',') numbers = [int(n) for n in user_input]

Use Regex import re input_string = input("Enter numbers: ") numbers = re.findall('([0-9])',input_string) print(multiply_num(*numbers))
