Explanation
The códe will be like this
print(3 + 2 * 2)
Output
7
Let's solve the mathematical expression inside print()
3 + 2 * 2
3 + 4

These expressions are solved according to the operator's precedence in Python. By precedence, it means which operator will be solved first in expression.
Precedence from highest to lowest (of basic operators) is as follows:
1. Parentheses ((), [], etc.)
2. Exponent (**)
3. Multiplication, Division, Floor division, Modulus (*, /, //, %)
4. Addition, Subtraction (+, -)
Extra Information
There are various types of Arithmetic Operators in Python such as
(A) + operator
It is used to add two operands
Example
print(5+3)
The output will be 8
(B) - operator
It is used to subtract two operands
Example
print(5-3)
The output will be 2
(C) * operator
It is used to multiply two operands
Example
print(5*3)
The output will be 15
(D) / operator
It is used to divide the operands and will give the output in float or decimal value.
Example
print(5/3)
The output will be 1.6666666666666667
(E) // operator
It is used to divide the operands and will not give the output in float or decimal value even if required. It only gives integer value as output.
Example
print(5//3)
The output will be 1
(F) % operator
It is used to divide the operands and return the remainder
Example
print(5%3)
The output will be 2
(G) ** operator
It is used to raise one operand to the power of another.
Example
print(5**3)
The output will be 125
In mathematical terms, it will be like 5³ which is 125
Python is created by Guido van Rossum and came into existence in 1991. It is a high-level and general programming language. It is a very lucid programming language as it has a good language construct and object-oriented approach. It is dynamically typed and garbage-collected.
