Question

How to work with dictionary and modules

Answer 1

You can learn them in Python courses, such as Python Developer: https://www.sololearn.com/learn/courses/python-developer

Still here's the basics:

Dictionary:

Dictionary is a collection of key-value pairs, each key holding a value. Like here, where name holds "Alan" and age holds 20:

person = {
"name": "Alan",
"age": 20
}

Access values:

print(person) # Outputs the dictionary
print(person["name"]) # Outputs "Alan"

Add, update and remove values:

person["name"] = "John" # Value of 'name' is "John"

person["profession"] = "Programmer" # Added new key 'profession' with value "Programmar"

person.pop["age"] # Removes the key-value pair of "age"

Module:

Modules are files that have variables, classes, functions and more set-up in a way that you can reuse them in your code to make tasks easier and optimized.

Import a module with import:

import math

Using a math function:

print(math.sqrt(25)) #square root of 25

Answer 3

Creating a module: Save your functions or variables in a .py file, and you can import them into other Python scripts.

Importing modules: You use the import keyword to access the functionality of the module.

Using functions from the module: You can call the functions or access variables as needed.
