# Python Ternary Operator for One-Line If-Else Logic

> Use a conditional expression like x = 1 if condition else 0 for Python's equivalent of the ternary operator found in C-like languages such as Java

## The Problem

Many C-like languages include a ternary operator, which is used for expressing simple if-then-else statements in a single line. It usually looks something like this:

```c
int x = b == true ? 1 : 0 // if b == true, x = 1; else x = 0
```

Is there a way to do this in Python?

## The Solution

Yes, Python supports inline conditional assignments using a form of the ternary operator, usually called a *conditional expression*. The syntax is as follows:

```python
x = 1 if b == True else 0

# or

x = 1 if b else 0
```

In this code, if `b` is true, `x` will be set to `1`, otherwise `x` will be set to `0`.

Similarly, simple if statements can be written on a single line:

```python
if b == True: x = 1
```

However, this syntax is unusual and does not allow for the inclusion of an else clause on the same line. Conditional expressions should be preferred for simple assignments, and more complex code should be split across multiple lines.

```python
if b == True:
    x = 1
    print("b is True and x is 1")
else:
    x = 0
    print("b is False and x is 0")
```
