PEP8 Guidelines Python Clean Coding - Exercise 1: Inputs and Logical Operations

The video tutorial guides students through an assignment where they create a program to subtract two numbers input by the user. The instructor explains how to use float inputs for decimal numbers and demonstrates the subtraction process. The result is printed as a string, and the video concludes with a brief introduction to conditional statements for checking if the result is positive or negative.

What is the main task assigned in the first section of the video?

• To add two numbers

• To subtract one number from another

• To multiply two numbers

• To divide two numbers

Why is the 'float' function used when taking input from the user?

• To ensure the input is a string

• To allow the input to have decimal points

• To make the input uppercase

• To convert the input to an integer

What is the purpose of converting the subtraction result to a string before printing?

• To add a decimal point to the result

• To make the result bold

• To change the result to an integer

• To ensure it can be concatenated with other strings

What additional feature is briefly introduced in the third section?

• Adding a user interface

• Multiplying the result by a constant

• Using conditional statements to check the result

• Looping through numbers

In the example provided, what is the result when the first number is 10 and the second number is 7?

• 0.3

• 17

• 3

• 70
