In python if the user doesn't enters a input and simply press submit button. If this is situation then how to set default value?

How can we add value to input if user forget to do it? https://code.sololearn.com/c1SFki1nKU1O/?ref=app

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😊😊😊 https://code.sololearn.com/cXNshChP7mzu/?ref=app

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

#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

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

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

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

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.

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,...

Try this dude: a = input() if len(a) is 0: a = 'value' I think this the possible way in Sololearn

Python is also case sensitive sir. Exactly whats in the quotes above is what needs to be replaced
