In Python, as in other programming languages, the flow of execution is controlled by statements. Statements are instructions that tell the Python interpreter what to do. The most common type of statement is the assignment statement, which assigns a value to a variable. Other types of statements include if statements, for statements, and while statements.

In this article, we’ll take a closer look at how control flow works in Python. We’ll learn about the different types of control flow statements and how to use them. We’ll also learn about loops and conditionals, which are two important concepts that you need to understand in order to write effective Python code.

Assignment Statements

An assignment statement is a statement that assigns a value to a variable. In Python, the assignment operator is the equal sign (=).

For example, the following code assigns the value 5 to the variable x:

x = 5

You can also assign values to multiple variables at once:

x, y, z = 1, 2, 3

If Statements

An if statement is a type of control flow statement that allows you to execute code only if a certain condition is true. If the condition is false, the code in the if block will not be executed.

Here’s an example of an if statement:

if x == 5:

print(“x is equal to 5”)

In this example, we’re checking to see if the value of x is equal to 5. If it is, we print out a message saying “x

For Statements

A for statement is a type of control flow statement that allows you to execute code multiple times. The code in the for block will be executed once for each item in a given sequence.

For example, let’s say we have a list of numbers:

numbers = [1, 2, 3, 4, 5]

We can use a for loop to print out each number in the list:

While Statements

While statements are a type of control flow statement that allows you to execute code multiple times. The code in the while block will be executed as long as the condition is true.

Here’s an example of a while loop:

i = 1

while i <= 10:

print(i)

i += 1

In this example, we’re printing out the numbers from 1 to 10. We do this by setting up a variable

Loops

A loop is a type of control flow statement that allows you to execute code multiple times. The code in the loop will be executed once for each item in a given sequence.

There are two types of loops in Python: for loops and while loops.

For example, let’s say we have a list of numbers:

numbers = [1, 2, 3, 4

Conditionals

Conditionals are a type of control flow statement that allows you to execute code only if a certain condition is true. If the condition is false, the code in the conditional block will not be executed.

There are two types of conditionals in Python: if statements and while statements.

If StatementsAn if statement is a type of conditional that allows you to execute code only if a certain condition is true. If the condition is false, the code in the if block will not be executed.

In this article, we’ve learned about the different types of control flow statements and how to use them. We’ve also learned about loops and conditionals, which are two important concepts that you need to understand in order to write effective Python code.
