Can anyone explain

Question

Hi all,
I have been doing a lot of challenges could anyone make sense of this for me.

a = "solo"
print(a.zfill(6))

Answer 1

It pads the string left with zeros. The length of string "a" is 4 so it's padded left with 6-4 zeros => "00solo".
You can find more info here: https://www.tutorialspoint.com/JUMP_LINK__&&__python__&&__JUMP_LINK/string_zfill.htm
Hope it helps you.

Answer 2

zfill function help us to fill the zeros in start of the string.
zfill(x)--> here x refer to how many zeros you want to fill.

Output=x-len(string)
Now,
a='solo'
print(a.zfill(6))
Here you want to fill 6 zeros in front of the (a)string and output will be 6-4=2 means total 2 zeros will be add because 4 is length of the a variable and output =x-len(string)
Output="00solo"

Answer 3
