Modules in Python

The video tutorial covers the creation and usage of Python modules, starting with a custom module named my_module1. It explains how to import and access functions and variables from modules. The tutorial then introduces built-in modules like datetime for date and time operations, math for mathematical functions, and random for generating random numbers. Each module's key functions and their applications are discussed, providing a foundation for using these tools in Python programming.

What is the first step in using a custom module in another Python file?

• Define all functions in the main file

• Import the module using the import statement

• Rename the module before using it

• Copy the module code into the main file

Which function from the datetime module returns the current date and time?

• datetime.today()

• datetime.now()

• datetime.time()

• datetime.current()

What does the math.sqrt function do?

• Rounds a number to the nearest integer

• Finds the factorial of a number

• Returns the square root of a number

• Calculates the square of a number

Which function from the random module generates a random integer within a specified range?

• random.randint()

• random.range()

• random.random()

• random.int()

What is the purpose of the math.ceil function?

• To generate a random floating-point number

• To find the smallest integer greater than or equal to a number

• To find the largest integer less than or equal to a number

• To calculate the power of a number
