How to format list to str? Python

Question

For example: [1,2,3,4,5]
To
"12345"

Answer 1

lst =[1, 2, 3, 4, 5]
print(''.join(str(i) for i in lst))
# 12345

Answer 2

l = [1,2,3,4,5]

s = ''.join(map(str, l))

print(s) # '12345'

Answer 3

You can also use loops:
list_x = [1, None, True, "Hello"]
string_x = ""
for i in list_x:
string_x += str(i)

"1NoneTrueHello"

But often using "".join(list) is more recommended, because string is an immutable object, each time you ran string_x += str(i) would destroy and create a new string in each iteration of the loop. I would expect builtin str.join to perform it smarter.

Answer 4

l = [1,2,3,4,5]
print(*l, sep = '')

# result: 12345
