Python f-strings basics and examples

🚀 Using Boolean Operators to Create Complex Conditions (Python) Boolean operators such as 'and', 'or', and 'not' can be combined to create complex conditional expressions. 'and' requires both operands to be True for the entire expression to be True. 'or' requires at least one operand to be True. 'not' negates the value of its operand. Understanding how to combine these operators is essential for creating sophisticated control flow logic that accurately reflects the desired program behavior.

Two sum: Using dictionary (Optimized Solution) Instead of checking every pair: For each number, calculate what number is required. Formula to calculate required : required = target - current_number  Time complexity → O(n) #Python #LogicBuilding #ProblemSolvingSkills #Beginners

Remember, #Python f-strings are strings: 1. Use f-strings anywhere you'd use strings, e.g., filenames and URLs 2. You don't have to print an f-string; you can store it. 3. Don't overuse them! I see people writing print(f'{x}') when they can say print(x)

If a #Python string contains an ISO-formatted date, skip strptime and use datetime.fromisoformat: import datetime as dt dt.datetime.fromisoformat('2026-04-12') # returns datetime at midnight dt.datetime.fromisoformat('2026-04-12 12:34:56') # returns datetime at 12:34:56

Python Strings & Formatting String Formatting f-strings (Python 3.6+, recommended – cleanest): print(f"My name is {name} and I am {age}") # My name is Joy and I am 30 print(f"Next year, I will be {age + 1}") # Next year, I will be 31 String Methods phrase = "Hello World" print(phrase.lower()) # hello world print(phrase.upper()) # HELLO WORLD print(phrase.count('l')) # 3 print(phrase.find('World')) # 6 print(phrase.replace('World', 'Universe')) # Hello Universe Key Takeaways: - Multiple ways to format strings - f-strings = cleanest & recommended - Strings are immutable - .find() gives index, .count() counts chars #Python
