Getting Input In Python

 

• 
  

In Python, you can get input from the user using the built-in function input(). This function reads a line of text entered by the user and returns it as a string.

Basic Input Usage:

• Getting Input from the User:
  
  user_input = input("Enter something: ")

• print("You entered:", user_input)

1.  Here, the input() function displays the prompt message (in this case, "Enter something:"), waits for the user to type something, and then captures the input as a string.
   
   

2. Converting the Input to Other Data Types: Since the input is always returned as a string, if you need the input to be of a different type (such as an integer or float), you can convert it using functions like int() or float().
   
   

• Integer Input:
  
  age = int(input("Enter your age: "))

• print("Your age is:", age)

• 
  

• Float Input:
  
  height = float(input("Enter your height: "))

• print("Your height is:", height)

• 
  

Example: Getting Multiple Inputs:

You can get multiple inputs at once and process them:

• name, age = input("Enter your name and age: ").split(", ")

• print("Name:", name)

• print("Age:", age)

In this example, the split(", ") method splits the input string at the comma and space to separate the name and age.

Error Handling:

If the user enters a value that cannot be converted to the required type, you'll get an error. To handle this gracefully, you can use a try/except block.

• try:

•     age = int(input("Enter your age: "))

•     print("Your age is:", age)

• except ValueError:

•     print("Please enter a valid number.")

Example of Getting Input for a Simple Program:

Here's a simple program where you ask the user for their name and age, then calculate the year they were born:

• name = input("Enter your name: ")

• age = int(input("Enter your age: "))

• birth_year = 2025 - age

• print(f"Hello {name}, you were born in {birth_year}.")

Key Points:

• The input() function always returns a string.

• You can convert the string to other types like int(), float(), etc., as needed.

• You can use .split() to split a single input into multiple values.

• You can handle invalid input with try/except.
