Python conditions are can be used in multiple ways in Python. Two of the most common ways are using *if statements* and loops. In this Python tutorial, we will cover if statements and the logical conditions from mathematics.

## Python Logical Conditions

- Equal: a == b
- Not Equal: a != b
- Greater than: a > b
- Greater than or equal to: a >= b
- Less than: a < b
- Less than or equal to: a <= b

In the below Python if statements, a and b are the created variables that will be used to compare the logical conditions. This will test if *a* and *b* are equal, if *a* and *b* are not equal,if *a* is greater than *b*, if *a* is greater than or equal to *b,* if *a* is less than *b*, and if *a* is less than or equal to *b*.

**Input:**

a = 25 b = 10 equal = a == b not_equal = a != b greater_than = a > b greater_than_or_equal_to = a >= b less_than = a < b less_than_or_equal_to = a <= b print("\nPython Logical Condition Examples") print(f" First variable is: {a} ") print(f" Second variable: {b} ") print(f" a is equal to b: {equal} ") print(f" a is not equal to b: {not_equal} ") print(f" a is greater than b: {greater_than} ") print(f" a is greater than or equal to b: {greater_than_or_equal_to} ") print(f" a is less than b: {less_than} ") print(f" a is less than or equal to b: {less_than_or_equal_to} ")

**Output:**

Python Logical Condition Examples First variable is: 25 Second variable: 10 a is equal to b: False a is not equal to b: True a is greater than b: False a is less than b: True a is greater than or equal to b: False a is less than or equal to b: True

## Python Indentation

Python code needs four space of indentation, followed by a colon at the end of the statement. This is how one can tell Python is creating a new block of code, and then followed by four spaces of indentation. If the Python code is not indented properly, a syntax error will occur because after the colon, an indentation should occur in the block of code.

## Python If Statement

**Input:**

a = 25 b = 10 print("\nPython If Statement Examples") print(f" First variable is: {a}") print(f" Second variable: {b} \n") if a == b: print(" a is qual to b") if a != b: print(" a is not equal to b") if a > b: print(" a is greater than b") if a >= b: print(" a is greater than or equal to b") if a < b: print(" a is less than b") if a <= b: print(" a is less than or equal to b")

**Output:**

Python If Statement Examples First variable is: 25 Second variable: 10 a is not equal to b a is greater than b a is greater than or equal to b

### Python Keyword *AND* Logical Operator

The keyword AND logical operator is used to combine multiple conditional statements and all conditions must be met to be true.

**Input:**

print("\nPython AND Logical Operator Statement Examples") print(f" First variable is: {a}") print(f" Second variable: {b} \n") if a != b and a > b and a >= b : print(" All AND logical operator conditions are met.") print(" \ta is not equal to b") print(" \ta is greater than b") print(" \ta is greater than or equal to b")

**Output:**

Python AND Logical Operator Statement Examples First variable is: 25 Second variable: 10 All AND logical operator conditions are met. a is not equal to b a is greater than b a is greater than or equal to b

### Python Keyword *OR* Logical Operator

The keyword OR logical operator is used to combine multiple conditional statements, but only only one condition must be met to be true.

**Input:**

print("\nPython OR Logical Operator Statement Examples") print(f" First variable is: {a}") print(f" Second variable: {b} \n") if a == b or a != b or a > b or a >= b or a <= b : print(" One OR more of the conditions were met.")

**Output:**

Python OR Logical Operator Statement Examples First variable is: 25 Second variable: 10 One OR more of the conditions were met.

## Python If…Elif…Else Statement

From the above *if statement*, an *if…elif…else statement* can be executed. But the statement will only print out the first condition that is true, whereas the above printed out all conditions that are true because there were 6 separate if statements.

**Input:**

a = 25 b = 10 print("\nPython If...Elif...Else Statement Examples") print(f" First variable is: {a}") print(f" Second variable: {b} \n") if a == b: print(" a is qual to b") elif a != b: print(" a is not equal to b") elif a > b: print(" a is greater than b") elif a >= b: print(" a is greater than or equal to b") elif a < b: print(" a is less than b") else: print(" a is less than or equal to b")

**Output:**

Python If...Elif...Else Statement Examples First variable is: 25 Second variable: 10 a is not equal to b
