Statement

What is a Statement in Python?#

In Python, a statement refers to an instruction which the Python interpreter can execute. As a programming language, Python is an unambiguous set of instructions for completing a task, and each of these instructions is known as a statement.

Various types of Python statements include:

• Assignment Statements
• Conditional Statements
• Loop Statements
• Import Statements

Assignment Statements#

Assignment statements are used to (re)bind names to values and also modify attributes or items of mutable objects. In simple terms, they are used to define a variable and associate a value with it.

1x = 10   # x is a name which is bound to the value 10

Conditional Statements#

Conditional statements, also known as selection statements, allow the execution of a statement sequence based on the evaluation of a condition. The if, elif and else statements are the most common types of conditional statements in Python.

1if x > 0:   # If the condition (x > 0) is true, then execute the indented statement
2    print("Positive number")

Loop Statements#

Loop statements are used to repeatedly execute a block of statements as long as the condition remains true. for and while are the most common loop statements.

1for i in range(5):   # For each number i in range 0-4, print i
2    print(i)

Import Statements#

The import statement is used to include external modules into a Python script. When included, the functions and classes defined in the module can be used in the current script.

1import math   # math module is included. Now we can use functions defined in this module.
