what is the statement and expression in syntax?
In Python, a statement is a line of code that performs some action, such as assigning a value to a variable, printing output to the console, or controlling the flow of the program. Statements are the basic building blocks of a Python program.
An expression, on the other hand, is a piece of code that produces a value. Expressions can be used within statements, as well as on their own. For example, the expression 3 + 4 produces the value 7, which can then be used in a statement, like result = 3 + 4.
Here are a few examples of statements and expressions in Python:
python# Statement that assigns a value to a variable
x = 10
# Statement that prints output to the console
print("Hello, world!")
# Statement that controls the flow of the program
if x > 5:
print("x is greater than 5")
else:
print("x is less than or equal to 5")
# Expression that adds two numbers and produces a value
result = 3 + 4
# Expression that uses a built-in function to produce a value
len("Hello, world!")
In Python, expressions can be used within statements, such as in the example result = 3 + 4, where the expression 3 + 4 is used to assign a value to the variable result. Understanding the difference between statements and expressions is important for writing effective and efficient Python code.
