Loops in Python By  ienex In programming, instructions are generally executed sequentially , one after the other. However, there are situations where we need to repeat a block of instructions multiple times . This is where loops come into play in Python. What is a Loop? A loop is a control structure that allows a set of instructions to be executed repeatedly , based on a condition or over a sequence of items. Python provides several types of loops to handle different scenarios. Types of Loops in Python Loop Type Description while loop Repeats a block of instructions as long as a specific condition is true . The condition is checked before each iteration. for loop Iterates over a sequence or collection of items (like a list, string, or range) for a specific number of times. Nested loops Loops can be placed inside other loops to handle more complex repetitive tasks. Control Instructions for Loops Python provides special statements to control th...

Decision making in Python application Programming By  ienex Decision-making in programming involves evaluating conditions during program execution and taking appropriate actions based on those conditions. In Python, decision-making is typically done using logical expressions that evaluate to either True or False . The program then executes specific code depending on the result. How Python Evaluates Conditions In Python: Any non-zero value is considered True . A zero value or None is considered False . This allows Python to handle a wide range of decision-making scenarios efficiently. Decision-Making Structures in Python Python provides several control structures for decision-making: Statement Description if Evaluates a logical expression and executes a block of code if the expression is True . if ... else Provides alternative actions when the if expression is False . if ... elif ... else Allows multiple conditions to be checked se...
