How to call the same user input in different location in a print()

You can do like below:

print ((lambda x: x ** 3)(int(input("Please enter a Number"))))

If you don't assign input() value to a variable, you cannot retrieve it again.

Python 3.8

You can assign variables inside print statement.

print("The cube of " + (a := input("Please enter a Number")) + " is " + pow(a, 3))

Python < 3.8

You cannot do this in one statement only. Or maybe something like this:

print('{}\nThe cube of {} is {}'.format(exec('a=int(input("Please enter a Number"))'), a, pow(a, 3)))

You could assign the input value to a variable like this:

def main():

    enteredNumber = input("Please enter a Number")
    print("The cube of ", enteredNumber, "is", pow(int(enteredNumber), 2)) 


if __name__== "__main__":
  main()

You are getting the input prompt twice since you are using 'input' keyword twice.

The solution for that is, by getting input from user first and then printing cube:

num = int(input("Please enter a Number: "))
print("The cube of ", num, "is ", pow(num, 3))

This might come in handy for simple cases. But there are a lot more ways to get the desired output which helps a lot in complex cases.

Using % Formatting

print("The cube of %d is %d" %(num, pow(num, 3)))

Using str.format

print("The cube of {} is {}".format(num, pow(num,3)))

Using f-strings

print(f"The cube of {num} is {pow(num,3)}")

All the above methods will give you the same result. You can read more about them in a simpler way here.

If you really want to do this in a single line of code, you can use a lambda function with f-strings to achieve it like this:

print((lambda num: f"The cube of {num} is {pow(num,3)}")(int(input("Please enter a Number: "))))

All the best in learning and mastering Python.

You can use assignment expressions to capture and pass-on the input:

print("The cube of ", (num := input("Please enter a Number")), "is", pow(int(num), 3))

Note that one would usually do that with multiple lines:

num = input("Please enter a Number")
print("The cube of ", num, "is", pow(int(num), 3))

Since you are insisting on "single" line of code, my following suggestion is somewhat close. This will work on Python 3.x

print(list(map(lambda x:x**3,[x for x in [int(input())]])))

Ideally you should split this into two lines.

Edit inspired by Vijesh's answer

Vijesh, in this post, has given a very succinct answer to accomplish the same. Below is the same code but omitting any use of variable name.

print((lambda _ : _**3)(int(input())))
