Answer 1

B.Naresh Kumar before you hit the submit button you have to follow some steps only in sololearn

Since, your code takes 3 input from the user. So while submitting the values you enter the values in new line

Eg -
42
23
32

So, if you want that your code gives the output even if the user doesn't input any value(default value), then still you have to enter space according to your input

Eg -
(Enter)
(Enter)
(Enter)

I think your doubt may be cleared now😊😊😊

choice = input("") or 7
choice takes input if not empty, otherwise 7.

Divyanshu Singh sure bro😊😊

Answer 6

#B.Naresh Kumar look at this once:

#if only single input needed, use
num1=int(input() or 70)

#for more inputs use try,catch like

try:
num2=int(input())
num3=int(input())
except :
num2 =30
num3 =20

Answer 8

One thing I like about Python is precisely the fact that you can do this in a rather elegant way.
For example if input is stored in variable n you can do:
n=int(input() or 5)
If the user just press Submit, then n will be set to 5

Answer 9

n = [1,2,3]
choice = input('Pick a number from 1-3')
if choice == '' or choice not in n:
choice = 1

Slick and Jayakrishna🇮🇳 please give your answer according my code .I edited the qn.😊

Answer 11

You must be a beast with another language haha. Python uses "None" in place of "null"

Answer 12

Slick it doesn't worked☹️

Answer 13

Slick replaced but literal error☹️

Answer 14

Theres a bunch of ways to do this but im not trying to rewrite your code my man. You just called in a squad so Ill write my version of the program and you can see if theres anything to implement.

Answer 15

I did not find any mistake.
It's working well.
May be , I don't understand what you are asking!😀

Answer 16

B.Naresh Kumar what problem you are getting still..
If only single input need then use or method..
Because a press enter treated as empty string...
If multiple inputs, then go for try catch method,...

Answer 17

Try this dude:

a = input()
if len(a) is 0:
a = 'value'

I think this the possible way in Sololearn

Answer 18
