Python For Absolute Beginners & Pass The PCEP Exam

Define the Python programming language, explore its uses, identify the jobs that use Python, and learn about certification in Python.

Discover why Python, one of the easiest programming languages for beginners, is ideal for absolute beginners due to its beginner-friendly syntax, wide use, and robust community that fuels job opportunities.

Learn multiple ways to run Python scripts, including from the command line, executing files with proper permissions and shebang, using Python -m, and testing in online editors.

Learn Python variable name rules: start with a letter or underscore, not a number or keyword. Names are case sensitive; use alphanumeric characters and underscores, snake or camel case.

Output variables with the print function, using comma separation for multiple values, and noting the default space; compare the plus operator vs printing with numbers and strings in Python.

Define global variables outside a function and access them inside and outside its scope. Use the global keyword inside a function to modify a global variable across the file.

Explore Python's numeric types - integers, floats, and complex numbers. Verify types with type() and convert between types using int, float, and complex, then generate random numbers with the random module.

Explore casting in python with int, float, and str constructors, convert floats and strings to integers, handle invalid literals, and convert strings via float before int.

Learn how to concatenate strings in Python using the plus operator, create combined text, and add spaces for readability.

Learn Python comparison operators: equal, not equal, greater than, less than, greater than or equal to, and less than or equal to through clear examples.

Practice shorthand for if statements and ternary operators in python, using single-line if and else expressions to print a or b based on comparisons, including multi-branch conditional examples.

This lecture introduces nested statements in Python, including nested for loops, nested if statements, and inner functions, and explains using pass to avoid empty blocks in PyCharm.

Explore Python while loops, using conditions to control execution, with break to exit, continue to skip iterations, and else blocks, demonstrated through practical debugging in PyCharm.

Explore how to modify Python lists by index and by range, replace multiple items with new values, and insert items with the insert method, observing how list length updates.

Learn to add items to a Python list using append, insert at an index, and extend to combine lists or other iterables, with examples like apple, orange, banana, and kiwi.

Join tuples in Python using the plus operator and repeat tuple contents with the asterisk operator, with practical PyCharm examples showing two-tuple concatenation and threefold replication.
