Learn Python From Basic to Advance.

Install Python on macOS by downloading the latest version from python.org/downloads and selecting from available releases. Verify that macOS includes Python, and consider Bolton Python for compatibility with Apple computers.

Write and run your first Python program using the print function to display text like 'Hello user,' confirming Python is installed and the Python shell is working.

Learn how to use variables to store integer and float values in Python and perform arithmetic. See examples of adding numbers, printing results, and distinguishing between integer and decimal types.

Learn how to use the backslash escape character in Python strings to print double quotes within a print statement, and understand basic string handling and escaping in Python.

Explore how to replace text in Python using the string replace method and the built-in replace function, with practical ABC string examples.

Use the string find method in Python to locate a substring, understand 0-based indexing, and determine the position of the word within a text.

Explore how to use if statements in Python to make decisions based on conditions, print results when true, and skip actions when false, with practical examples.

Learn how the Python for loop iterates with a loop variable and a condition, printing items in sequence from numbers to letters while noting case sensitivity.

Master while loops in Python by iterating from 1 to 5, updating the counter, and printing each value, with an optional else clause to handle termination.

Learn how to use the range function in Python to generate lists of integers, starting from zero to print 0–9, and starting at 20 to print 20–24.

Discover how to use the built-in len function to get the total number of elements in a Python list, with a practical example that prints the length.

Learn how to remove elements from a Python list using the remove method and the del statement, including removing the first occurrence and zero-based indexing.

Learn how to use the Python append method to add elements to a list, and see before and after examples that show the appended items.

Learn to sort lists in Python with the built-in sort method, demonstrating ascending and descending order using reverse=True and printing lists before and after sorting.

Learn how the len method returns the number of items in a dictionary and view the actual items—Ali, John, and Mary—in a hands-on Python example.

Explore removing all items from a dictionary with the clear method, print the dictionary before and after clearing, and inspect its keys with the built-in keys function.

Use the Python set method to remove duplicates from lists and dictionaries, illustrated by an employee record example where duplicates disappear.

Learn how arrays in python behave like lists but hold single-type elements, perform zero-based indexing and slicing, and concatenate and access elements using index ranges.

Learn to import and use the Python array from the standard array module, create an array of numbers, and iterate with a for loop while noting zero-based indexing.

Discover how to remove items from a Python array using the pop method, including removing by 0-based index and observing the array before and after removal.

Learn how Python's built-in open function creates a file object to read or write files, use modes like read and read-write, and print file contents.

Learn to write to a Python file using the write method, open and close the file, then reopen it to read and verify the written content, including newline handling.

Install the latest python on your mac by downloading from python.org, open the idl environment, create and save a python project, and run a test print to verify the setup.
