## Python OR

To perform logical OR operation in Python, you can use **or** keyword.

In this tutorial, we shall learn how Python **or** logical operator works with boolean values and integer operands, with the help of example programs.

### Syntax – or keyword

The syntax to use **or** operator is given below.

`operand1 or operand2`

**or** logical operator accepts two operands.

**or** operator returns true if any of the operands is true.

### Truth Table – OR Logical Operation

Following is the truth table with the Return values for possible combinations of the operands to OR operator.

Operand1 | Operand2 | Return Value |

True | True | True |

True | False | True |

False | True | True |

False | False | False |

To summarize, if any of the operands is True, then OR operator returns True.

### Example 1: Python Logical OR

Following example, demonstrates the usage of **or** keyword to do logical **or** operation. In this example, we take two variables and their possible logical value combinations.

**Python Program**

```
#True or True
a = True
b = True
c = a or b
print(a,'or',b,'is:',c)
#True or False
a = True
b = False
c = a or b
print(a,'or',b,'is:',c)
#False or True
a = False
b = True
c = a or b
print(a,'or',b,'is:',c)
#False or False
a = False
b = False
c = a or b
print(a,'or',b,'is:',c)
```

Run **Output**

```
True or True is: True
True or False is: True
False or True is: True
False or False is: False
```

### Example 2: OR Operator with non-boolean operands

When using in boolean expressions, you can also use non-zero number for True and zero for False.

**Python Program**

```
#True or True
a = 5
b = -5
c = a or b
print(a,'or',b,'is:',c)
#True or False
a = 4
b = 0
c = a or b
print(a,'or',b,'is:',c)
#False or True
a = 0
b = 6
c = a or b
print(a,'or',b,'is:',c)
#False or False
a = 0
b = 0
c = a or b
print(a,'or',b,'is:',c)
```

Run **Output**

```
5 or -5 is: 5
4 or 0 is: 4
0 or 6 is: 6
0 or 0 is: 0
```

### Summary

In this tutorial of Python Examples, we learned about **or** logical operator in Python, and how to use it, with the help of well detailed examples.
