Question

I first wrote the code
x = input()
print("You entered: " + x)
Suppose one entered 8
Result was - You entered: 8
But when i changed code to
x = input(int())
print("You entered: " + x)
It came
0You entered: 8
Can anyone explain?

Answer 1

x = input()
print(type(x))

print(help(int()))

Answer 2

Same answer than what I replied in the other Q&A. https://www.sololearn.com/Discuss/3010045/?ref=app

It is due to execution order. The code in the deepest parenthesis is running first in our case.

int(input()) : input() runs first and prompt the user to enter a value, then turns the input into an integer.

input(int()) : int() runs first and because nothing is mentioned inside the parenthesis, it automatically generate an integer with the value 0 then finally run input().

The reason why 0 is printed is because input() basically prints what is inside its parenthesis while waiting for user to enter a value.

Answer 3

Just messing with the codes of excercise 14.1 python for beginners

Answer 4

Anything as argument to function input() is just displayed on the console. It's helpful for display information about asking input()
like :

name = input( "Enter your Name")
s = input("Enter a string")
n = int( input(" Enter a number")) #if you are taking a number, you need to type cast to int ..
age = int( input())

try these tests and print input and see output..
Hope it helps..

Answer 5

print(int()) #returns 0 , if no argument to int(), it returns 0, which is given as argument to input() , and it's just displayed on console..

what are you actually trying!?
