If you have to take user input from keyboard in Python that can be done using input() function. Python input() function takes the entered value and returns it as a string once user presses Enter.
Syntax of input() function
The syntax of Python input() function is
Here msg is the optional string that is displayed on the console.
User input in Python example
val = input('Please enter your name: ') print('Entered Value- ', val)
Please enter your name: knpcode Entered Value- knpcode
Input as number in Python
Note that input() function always returns entered value as string. If you want to get the value as integer or float you need to convert it explicitly.
val = input('Please enter a number: ') # Convert to int val = int(val) # now use in arithmetic operation print(val+5)
Please enter a number: 8 13
You can use int() function along with the input() function to shorten the code-
val = int(input('Please enter a number: ')) # now use in arithmetic operation print(val+5)
For float numbers you can use float() function
val = float(input('Please enter a number: ')) # now use in arithmetic operation print(val+5)
Multiple values as input in Python
You can write separate input() functions to take more than one inputs from user. But Python provides a shorter version by using for loop along with input() function to take multiple inputs. Entered values are parsed as separate values by using split() method which considers space as delimiter by default. Therefore separate the separate inputs by space.
num1, num2, num3 = [int(x) for x in input('Please enter three integers: ').split()] print('Sum of entered numbers-', (num1+num2+num3))
Please enter three integers: 4 5 6 Sum of entered numbers- 15
