Here are some cool Python tricks: Formatted string literals: Also known as F-strings, this feature allows you to embed expressions directly into string literals. This makes string formatting more readable and expressive. Merging dictionaries: You can merge dictionaries using the update() method. Python profiling: This feature allows you to track memory usage, measure the number of function calls, and analyze the time needed for the execution of those calls. Concatenation: You can use the join() method to concatenate strings. Counting objects using a counter: You can use the Counter object to count the occurrences of elements in a collection. Splitting a string: You can use the str.split() method to divide a string into a list of substrings. Using itertools: This standard library provides functionality to create fast, memory-efficient, and good-looking code. Using map and filter: You can use the map and filter functions to apply a process to each element of a list and filter elements, respectively. Slicing: You can use slicing to take elements from one given index to another given index. read less

  1. Swap variables: 
    a, b = b, a

    squares = [x*x for x in range(10)]
  3. Reverse a string: 
    reversed_str = "hello"[::-1]
  4. Using zip() to combine lists: 
    pairs = list(zip([1, 2, 3], ['a', 'b', 'c']))
  5. Unpacking: 
    a, b, *rest = [1, 2, 3, 4, 5]
