Python Expressions
Python Expressions
Python expressions are valid combinations of operators and operands like literals, variables, and functional calls. Expressions need to be evaluated, and they always return a value.
Types of Python Expressions
Expressions can be classified into two main categories:
- Simple Expressions
- Compound Expressions
Compound expressions are expressions formed by one or more simple expressions. Python expressions can be of the following types based on the operators used:
- Arithmetic Expressions
- String Expressions
- Relational Expressions
- Boolean Expressions
- Logical Expressions
- Function Calls
- String concatenations
- Lambda Expressions
Expressions are the building blocks of Python programs, and they can be as simple as a single variable or as complex as a combination of various operations—a combination of two or more expressions forms compound expressions.
Examples
Example Python code:
# Python Expressions
# Python Tutorials – www.TestingDocs.com
def square(x):
    return x ** 2
x = 7
y = 9
result = x + y # Arithmetic Expression
print(result)
flag1, flag2 = True, False
bool_result = flag1 and flag2 # Boolean Expression
print(bool_result)
func_result = square(16) # Function call
print(func_result)
