# How to Convert a Character to an Integer and Vice Versa in Python

This tutorial discusses methods to convert a character to an integer and an integer to a character in Python.

## Use `chr()` to Convert an Integer to a Character in Python

We can use the built-in function `chr()` to convert an integer to its character representation in Python. The below example illustrates this.

``````val = 97
chr_val = chr(val)
print(chr_val)
``````

Output:

``````a
``````

It will result in an error if you provide an invalid integer value to this. For example:

``````val = 1231232323
chr_val = chr(val)
print(chr_val)
``````

Output:

``````---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-42-f76a9ed55c90> in <module>
1 val = 1231232323
----> 2 chr(val)

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

Therefore, it is always good to put this code in a `try...except` block to catch the error, if any, and avoid any crash. The below example illustrates this:

``````val = 1231232323
try:
chr_val = chr(val)
print(chr_val)
except Exception as e:
print("Error:", e)
``````

Output:

``````Error: chr() arg not in range(0x110000)
``````

## Use `ord()` to Convert a Character to an Integer in Python

We can use the built-in function `ord()` to convert a character to an integer in Python. The below example illustrates this.

``````val = "a"
try:
int_val = ord(val)
print(int_val)
except Exception as e:
print("Error:", e)
``````

Output:

``````97
``````

The above method also catches any invalid input and prints out the error instead of crashing the code. For example:

``````val = "aa"
try:
int_val = ord(val)
print(int_val)
except Exception as e:
print("Error:", e)
``````

Output:

``````Error: ord() expected a character, but string of length 2 found
``````
