Introduction to Python User Input
Python User Input
You can use the input()
function to prompt the user for input from the console.
The `input()
function reads a line of text entered by the user and returns it as a string.
As an example:
user_input = input("Enter your name: ")
print("Hello, " + user_input + "!")
In this example:
- The
input()
function prompts the user to enter their name. - The text inside the parentheses, "Enter your name: ", is the prompt displayed to the user.
- The user's input is then stored in the variable
user_input
. - Finally, the program prints a greeting message using the user's input.
The input()
function can also be used without displaying a prompt.
As an example:
user_input = input()
print("You entered:", user_input)
In this case:
- The
input()
function reads a line of text from the user without displaying any prompt. - The user's input is stored in the
user_input
variable, and then it is printed.
It's important to note that the input()
function always returns a string, even if the user enters a numeric value.
If you need to perform numerical operations on the user's input, you may need to convert it to the appropriate data type using functions like int()
or float()
.
user_input = input("Enter a number: ")
number = int(user_input)
double = number * 2
print("The double of", number, "is", double)
In this example:
- The user is prompted to enter a number.
- The input is read as a string, and then it is converted to an integer using the
int()
function. - The program then performs the multiplication operation and prints the result.
