Introduction to Python Inputs

Overview: Understanding Python Inputs

What are Inputs?

Inputs are simply data that the user provides to the computer. In Python, we use the input() function to get this data.

Key Concepts

  • Basic Input Function
    • The basic input function is: input()
    • Inputs are stored in variables for easy manipulation
    • Example usage:
      name = input()
  • Prompts
    • You can add a message inside the parentheses to tell the user what to type.
    • Example: input("Enter your name: ")

Understanding Inputs

This lesson covers how to convert input data types, particularly focusing on converting string inputs to integers and floats.

Understanding Input Data Types:

By default, the input() function returns a string. Even if the user types a number, Python treats it as text.

Converting Strings to Integers:

To convert a string input to an integer, use the int() function:

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

Converting Strings to Floats:

To convert a string input to a decimal number (float), use the float() function:

price = float(input("Enter the price: "))
