What is output of below snippet and how ?

Question

a=str([1,2,3,4])
print (len(a))

Answer 1

You can find out WHAT the output is by actually RUNNING the code. Count the number of characters in the string and you find out why it is like that.

Answer 2

print(a)

Then count.

Answer 3

Output is expected when you run the code.

If you get an error, LINK your complete code. Check the indentation. Check the spellings. Check for unmatched brackets.

Answer 4

Quoting myself:

Count the number of characters in the string and you find out why it is like that.

Answer 5

space is inbuilt here if we use 2 space then also it counts as 1

for ex
a= str([2, 3, 4])
print(len(a))

ans is 9

if

a= str([2,3,4])
print(len(a))

then also ans is 9

Answer 6

Output is not expected please explain

Answer 7

I think output is 4

Answer 8

How output is 12

Answer 9

no output is not 12 it's wrg

Answer 10

Please run the code

Answer 11

Chara are 9 only

Answer 12

sry, output is 12 because if we convert the list to string then it counts character, comma, square bracket, and space also.. it counts 12 so ans is 12

Answer 13

Where is space

Answer 14

or if we use no space then also it count 1

Answer 15

Answer 16

I lv this compliment, thanks 🙂

Answer 17

It appears that the python complier automatically adds a space after each ( , ) ;
So, there is a total of 12 characters (including the opening and closing brackets, commas, spaces, and digits).

1. [
2. 1
3. ,
4. space
5. 2
6. ,
7. space
8. 3
9. ,
10. space
11. 4
12. ]

Answer 18

I agree with Ritu rani
Perhaps Python's list __str__ or __repr__ method always adds spacing between items.

why not simply use

print(len('[1,2,3,4]')

or if you must use str()

a=str([1,2,3,4]).replace(' ','')
print(len(a))
