In Python, a for loop is used to iterate over a sequence, such as a list, tuple, string, or range. The general syntax for a for loop is as follows: for item in sequence: # code to be executed for each item Here, "item" is a variable that represents each individual element in the sequence, and "sequence" is the collection of items to iterate over. For example, let's say we have a list of numbers and we want to print each number using a for loop: numbers = [1, 2, 3, 4, 5] for num in numbers: print(num) Output: 1 2 3 4 5 You can also use the `range()` function to generate a sequence of numbers and iterate over it using a for loop. For example: for i in range(1, 6): print(i) Output: 1 2 3 4 5 In this example, `range(1, 6)` generates a sequence of numbers from 1 to 5 (inclusive), and the for loop iterates over each number and prints it. Note that the code inside the for loop is indented, which is essential in Python to define the block of code that should be executed for each iteration.
