Inputs

Step 1 of 4

Exercise 1: Understanding Inputs

Inputs are simply data that the user provides to the computer. This can be incredibly useful as they can be used for many things.

Here is the basic input function:

input()

Inputs are stored in variables from where they can be easily manipulated to perform other tasks.

variable = input()

Inside the brackets of the input function, you must place the input message, which simply prints before you ask the user for their input.

input("Please enter your name: ")

Try it Yourself

Practice writing different input statements!

Starter code

# practice writing a variety of input statements!
variable1 = # TODO: replace and write an input statement
variable2 = # TODO: replace and write a second input statement
variable3 = # TODO: replace and write a third input statement

# TODO: print the three variables

Exercise 2: Input Conversion

Inputs always come out as a string, which means that if you only input a number, you cannot perform any actions on it besides the string concatenation since the integer is now a string.

Luckily, coding languages provide a function which turn the strings to the integers (if there are components of a non-integer, or words, in the string, it will provide an error).

The int() function converts the string into an integer.

int(input("Type a number"))

The float() function converts the string into a float.

float(input("Type a decimal"))

Try it Yourself

Write a Python program that asks the user for their name and age, and then prints a message greeting them and stating their age.

Starter code

# write a program to ask the user for their name and age
name = #TODO
age = #TODO
print(f"Hello, {name}! You are {age} years old.")

Guided Exercise: Temperature Converter

Let's create a simple temperature converter that converts Celsius to Fahrenheit. We'll guide you through the process step by step.

The formula to convert Celsius to Fahrenheit is: F = (C * 9/5) + 32

Follow these steps:

Ask the user for a temperature in Celsius using input()
Convert the input to a float using float()
Apply the conversion formula
Print the result

Complete the code below to create the temperature converter:

Starter code

# Step 1: Ask for temperature in Celsius
celsius = # Step 2: Convert Celsius to Fahrenheit
fahrenheit =

# Step 3: Print the result
print(f"{celsius}°C is equal to {fahrenheit}°F")

Project: Personal Information Form

For this project, you'll create a program that collects personal information from the user and then displays it in a formatted manner. This project will test your knowledge of input functions, string concatenation, and basic Python syntax.

Your program should:

Ask for the user's name, age, and favorite hobby
Calculate the year the user was born (assume current year is 2023)
Create a sentence using string concatenation that includes all this information
Print the final sentence

Use your knowledge of Python to complete this project. Remember to use appropriate input functions and string formatting.

Starter code

# Personal Information Form
# Collect user's name, age, and favorite hobby
# Calculate birth year
# Create and print a sentence with all the information
