What is an operation in Python?
I'm happy to respond in English!
In the context of programming languages like Python, an operation refers to a specific action performed on one or more inputs (also known as operands) to produce a desired output. In other words, an operation is a fundamental building block that allows you to manipulate and transform data to achieve a particular goal.
Python, being a high-level language, provides various types of operations to simplify the process of performing tasks on data. These operations can be categorized into several groups:
Arithmetic Operations: Python supports basic arithmetic operations like addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and exponentiation (**). For example:a + b
, x - y
, or z * 4
are all valid arithmetic operations. Comparison Operations: These operations allow you to compare values using operators like <
, >
, ==
, !=
, <=
, >=
, and is
. For instance, x > 5
checks if the value of x is greater than 5. Logical Operations: Python's logical operations enable you to combine conditions using AND (and
), OR (or
), and NOT (not
) operators. For example: a > 0 and b < 10
evaluates to True only when both conditions are met. Assignment Operations: These operations update the value of a variable or attribute, such as x = 5
, which sets the value of x to 5. Bitwise Operations: Python's bitwise operations (e.g., ~
, &
, |
, ^
) manipulate binary representations of numbers. This is useful for tasks like checking if a number has a particular bit set or performing complex arithmetic operations. String Operations: String operations involve manipulating text using operators like +
(concatenation), *
(repetition), and in
(substring search). For example: "hello" + "world"
joins two strings together, while "abc" * 3
repeats a string three times. Membership Operations: These operations check if an object is present in a collection or has a specific attribute. The in
operator is used for membership testing, such as x in [1, 2, 3]
. Identity Operations: Python's identity operations (is
, !=
) compare the memory addresses of two objects to determine if they are identical.
These various types of operations form the foundation of programming in Python and allow you to write efficient, readable, and maintainable code. Understanding each operation's behavior is crucial for mastering the language and solving real-world problems effectively.

I'm happy to help you with that!
On W3Schools, an operation in Python refers to the actions performed on variables and values within a program to achieve specific goals or results. In other words, operations are fundamental building blocks of Python programming that enable you to manipulate data, perform calculations, and make decisions.
Python supports various types of operations:
Arithmetic Operations: These involve numerical values and mathematical operators (+, -, *, /, %) used for simple calculations. For example: x = 5
y = 3
print(x + y) # Output: 8
print(x - y) # Output: 2
print(x * y) # Output: 15
print(x / y) # Output: 1.6666666666666667 (float)
print(x % y) # Output: 2
Assignment Operations: These assign values or expressions to variables:
x = 5 # Assigns the value 5 to x
x += 3 # Equivalent to x = x + 3, now x is 8
y -= 2 # Equivalent to y = y - 2, now y is 1
Comparison Operations: These compare values or variables and return boolean (True/False) results:
print(x > y) # Output: True (x is greater than y)
print(y < x) # Output: True (y is less than x)
print(x == y) # Output: False (x is not equal to y)
Logical Operations: These evaluate conditions and return boolean results based on the truth of one or more statements:
if x > y and z < 2:
print("Condition True")
else:
print("Condition False")
Output: Condition True
Membership and Identity Operations: These check for membership in a sequence (list, tuple, dictionary) and identity between two values or variables:
if "apple" in fruits_list:
print("Fruit found")
else:
print("Fruit not found")
Output: Fruit found
x is y # Check for object identity
Bitwise Operations: These perform operations on binary data, such as shifting or combining bits:
a = 0b10101010
b = 0b11001100
print(a & b) # Output: 0b10000010 (binary AND)
print(~a) # Output: -105 (two's complement of binary value)
These basic operations form the foundation of Python programming, enabling you to write efficient, readable, and maintainable code.
