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 2

Sololearn doesn't allow module creation

Answer 4

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.

Steps to Create a Module in Python

1. Create a Python File (Module)

A module is just a .py file with some Python code.

Example: Create a file called mymodule.py and add the following code:

# mymodule.py

def greet(name):
return f"Hello, {name}!"

def add(a, b):
return a + b

pi = 3.14159

2. Import the Module in Another Python File

Now, you can import this module in another Python script and use its functions and variables.

Example: Create another Python file (main.py) and import mymodule:

import mymodule

print(mymodule.greet("Alice")) # Output: Hello, Alice!
print(mymodule.add(5, 3)) # Output: 8
print(mymodule.pi) # Output: 3.14159

3. Import Specific Functions or Variables (Optional)

Instead of importing the whole module, you can import only specific functions or variables:

from mymodule import greet, pi

print(greet("Bob")) # Output: Hello, Bob!
print(pi) # Output: 3.14159

4. Use an Alias for the Module (Optional)

You can rename the module while importing it using as:

import mymodule as mm

print(mm.greet("Charlie")) # Output: Hello, Charlie!
