if statement and if Else statement in python
In Python, the `if` statement is used for conditional execution of code. It allows you to specify a condition, and if that condition is true, the code block associated with the `if` statement is executed. Here's the general syntax of an `if` statement:
```python
if condition:
code to be executed if the condition is true
```
If you want to provide an alternative code block to be executed when the condition is false, you can use the `else` statement. Here's an example:
```python
if condition:
code to be executed if the condition is true
else:
code to be executed if the condition is false
```
Alternatively, you can use an `elif` statement (short for "else if") to specify additional conditions to be checked. The `elif` statement is useful when you have multiple conditions to consider. Here's an example:
```python
if condition1:
code to be executed if condition1 is true
elif condition2:
code to be executed if condition1 is false and condition2 is true
else:
code to be executed if both condition1 and condition2 are false
```
Note that you can have multiple `elif` statements if needed. The `else` block is optional and can be omitted if you don't need to specify code for the "false" case.
It's important to remember that indentation is crucial in Python. The code blocks associated with `if`, `elif`, and `else` statements must be indented properly to indicate their relationship with the conditions.
