To take input in Python, use the built-in input()<\/b><\/strong>\u00a0function: name = input(“Enter your name: “). It pauses the program, shows the prompt, waits for the user to type and press Enter, and returns what they typed as a string<\/b><\/strong>. To get a number, convert the result with int()\u00a0or float().<\/p>\n

What Is the input() Function in Python?<\/b><\/strong><\/h2>\n

input()<\/b><\/strong>\u00a0is a built-in function that reads one line of text from the keyboard (standard input). Its syntax is input(prompt), where the optional prompt is a message shown to the user.<\/p>\n

    \n
  • It always returns a str<\/b><\/strong>, even if the user types 42.<\/li>\n
  • The trailing Enter key (newline) is removed from the result.<\/li>\n
  • The program is paused until the user presses Enter.<\/li>\n<\/ul>\n

    How to Take User Input in Python (Strings)<\/b><\/strong><\/h2>\n

    Because input() already returns a string, taking string input needs no conversion:<\/p>\n

    name = input(“Enter your name: “)<\/p>\n

    print(f”Welcome, {name}!”)<\/p>\n

     <\/p>\n

    # Run:<\/p>\n

    # Enter your name: Rahul<\/p>\n

    # Welcome, Rahul!<\/p>\n

    To “give” input, run the script in a terminal or IDE, type your value after the prompt, and press Enter. In Jupyter, a text box appears below the cell.<\/p>\n

    How to Take Integer Input in Python<\/b><\/strong><\/h2>\n

    Wrap input() in int()\u00a0for whole numbers or float()\u00a0for decimals:<\/p>\n

    age = int(input(“Enter your age: “))<\/p>\n

    price = float(input(“Enter price: “))<\/p>\n

    print(age + 1, price * 2)<\/p>\n

    If the user types something that is not a number, int()\u00a0raises ValueError. Handle it with try\/except (see the Exception Handling topic).<\/p>\n

    How to Take List Input in Python<\/b><\/strong><\/h2>\n

    The most common method: read the whole line, split()\u00a0it into parts, and convert each part:<\/p>\n

    # User types: 10 20 30<\/p>\n

    nums = list(map(int, input(“Enter numbers: “).split()))<\/p>\n

    print(nums) \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0# [10, 20, 30]<\/p>\n

     <\/p>\n

    # Comma-separated: apple,banana,mango<\/p>\n

    fruits = input(“Enter fruits: “).split(“,”)<\/p>\n

    print(fruits) \u00a0\u00a0\u00a0\u00a0\u00a0# [‘apple’, ‘banana’, ‘mango’]<\/p>\n

    Alternatively, ask for the count first and read one item per line with a loop:<\/p>\n

    n = int(input(“How many items? “))<\/p>\n

    items = []<\/p>\n

    for i in range(n):<\/p>\n

    items.append(input(f”Item {i+1}: “))<\/p>\n

    print(items)<\/p>\n

    How to Build a Simple Calculator Using input() in Python<\/b><\/strong><\/h2>\n

    Part 2 \u2014 Tutorial<\/b><\/strong><\/p>\n

    In this tutorial you will build a calculator that reads two numbers and an operator from the user with input(), converts them, and prints the result. It takes about 15 minutes and 5 steps and uses input(), float(), if\/elif and print().<\/p>\n

    Prerequisites<\/b><\/strong><\/h3>\n
      \n
    • Python 3 installed and able to run a script from the terminal.<\/li>\n
    • Basic understanding of variables and print().<\/li>\n<\/ul>\n

      Steps<\/b><\/strong><\/h3>\n

      Step 1: Read the first number<\/b><\/strong><\/p>\n

      Convert the text to float so decimals work.<\/p>\n

      a = float(input(“First number: “))<\/p>\n

      Step 2: Read the operator as a string<\/b><\/strong><\/p>\n

      No conversion is needed; strip() removes accidental spaces.<\/p>\n

      op = input(“Operator (+ – * \/): “).strip()<\/p>\n

      Step 3: Read the second number<\/b><\/strong><\/p>\n

      Same conversion as step 1.<\/p>\n

      b = float(input(“Second number: “))<\/p>\n

      Step 4: Calculate with if\/elif<\/b><\/strong><\/p>\n

      Check the operator and guard against division by zero.<\/p>\n

      if op == “+”:<\/p>\n

      result = a + b<\/p>\n

      elif op == “-“:<\/p>\n

      result = a – b<\/p>\n

      elif op == “*”:<\/p>\n

      result = a * b<\/p>\n

      elif op == “\/” and b != 0:<\/p>\n

      result = a \/ b<\/p>\n

      else:<\/p>\n

      result = “Invalid input”<\/p>\n

      Step 5: Print the result<\/b><\/strong><\/p>\n

      Display it with an f-string, then run the script and test it with different inputs.<\/p>\n

      print(f”Result: {result}”)<\/p>\n","protected":false},"excerpt":{"rendered":"
