# How do I pad a string with zeroes in Python?

You can pad a string with zeros in Python by using the `zfill()` method. This method adds zeros to the left of the string until it reaches the specified length.

Here's an example:

```python
s = '123'
padded = s.zfill(5)
print(padded) # 00123
```

In this example, the string `s` is padded with two zeros on the left to reach a length of 5.
