๐Ÿ”ฅ Python Interview Concept You MUST Know: List Comprehensions

๐Ÿ“Œ The most important patterns:

๐Ÿ”น Basic List Comprehension โ†’ Create a new list in a single line

๐Ÿ”น Conditional Filtering โ†’ Keep only the elements that match a condition

๐Ÿ”น If-Else Expression โ†’ Transform values based on a condition

๐Ÿ”น Nested List Comprehension โ†’ Work with 2D lists and matrices

๐Ÿ”น Dictionary Comprehension โ†’ Create dictionaries efficiently

๐Ÿ”น Set Comprehension โ†’ Generate unique values automatically

๐Ÿ’ก Two keywords you'll use all the time:

PART 1: for โ†’ Iterates through each element

PART 2: if โ†’ Filters or transforms elements based on a condition

๐Ÿš€ Beginner tip: Master normal for loops first, then List Comprehensions will become much easier to understand and use.
