# chr() function in Python

## Introduction

The `chr()` function converts an integer to its unicode character and returns it.

The syntax of `chr()` function is:

```python
chr(num)
```

The `chr()` function takes in a single parameter **num** which is an integer in the range **0** to **1,114,111**. It can return the following:

*   **unicode character** of the corresponding integer if the integer value is in the range
*   **ValueError**, in the case integer value is out of range
*   **TypeError**, in the case a non-integer argument is passed

You can see the unicode representation of different characters [here](https://unicode-table.com/en/).

## Example 1

Let us pass integer arguments in the correct range.

```python
num1 = 65
print(chr(num1))

num2 = 120
print(chr(num2))

```

Output

```bash
A
x
```

In the above example, we have passed integers to the `chr()` function, and it returns the corresponding unicode characters.

## Example 2

Let us again pass integer arguments but this time, the values will be out of range.

```python
num = -65
print(chr(num))
```

Output

```bash
ValueError: chr() arg not in range(0x110000)
```

In the above example, we passed -65 as the argument, which is out of range, and hence it throws the **ValueError**.

## Example 3

Let us now pass something other than integer as the argument to the `chr()` function.

```python
print(chr('Hello'))
```

Output

```bash
TypeError: an integer is required (got type str)
```

As the error itself tells, an integer is required but we have passed string.

## Conclusion

In this part, we learned about the Python `chr()` function with the help of examples.
