Python Continue

The Python, the continue statement is used to skip the current iteration of a loop (either a for loop or a while loop) and proceed to the next iteration. It allows you to bypass the remaining code inside the loop for the current iteration and jump to the next iteration of the loop.

The basic syntax of the continue statement is as follows:

while condition:
    # Code before the continue statement
    if some_condition:
        continue
    # Code after the continue statement

Here’s how the continue statement works:

1. The while or for loop begins executing as long as the specified condition remains True.
2. Within the loop, you can use the continue statement when a specific condition (some_condition) is met.
3. When the continue statement is encountered, the loop skips the remaining code for the current iteration and immediately proceeds to the next iteration.

Here are a few examples of how the continue statement can be used:

Example 1: Skipping Even Numbers

for number in range(1, 11):
    if number % 2 == 0:
        continue
    print(number)

In this example, the for loop iterates through the numbers from 1 to 10. When it encounters an even number (i.e., a number divisible by 2), the continue statement is used to skip printing that number, and the loop proceeds to the next iteration.

Output:

1
3
5
7
9

Example 2: Skipping Specific Items in a List

fruits = ["apple", "banana", "cherry", "date", "fig"]
for fruit in fruits:
    if fruit == "date":
        continue
    print(fruit)

In this example, the for loop iterates through a list of fruits. When it encounters the fruit “date,” the continue statement is used to skip printing that fruit, and the loop proceeds to the next iteration.

Output:

apple
banana
cherry
fig

Example 3: Skipping Rows in CSV Data

csv_data = [
    ["Name", "Age", "City"],
    ["Alice", 25, "New York"],
    ["Bob", 32, "Los Angeles"],
    ["Carol", 28, "Chicago"],
]

for row in csv_data:
    if "Bob" in row:
        continue
    print(row)

In this example, the for loop iterates through a list of CSV data rows. When it encounters a row containing the name “Bob,” the continue statement is used to skip printing that row, and the loop proceeds to the next iteration.

Output:

['Name', 'Age', 'City']
['Alice', 25, 'New York']
['Carol', 28, 'Chicago']

The continue statement is a useful tool for controlling the flow of loops in Python when you want to skip certain iterations based on specific conditions. It allows you to customize the behavior of your loops and skip over items or sections of code as needed.
