# How do I parse a string to a float or int in Python?

To parse a string to a float in Python, you can use the `float()` function. This function takes a string as input and returns a floating point number constructed from it. For example:

```python
float('3.14') # returns float 3.14
```

To parse a string to an integer in Python, you can use the `int()` function. This function takes a string as input and returns an integer constructed from it. For example:

```python
int('42') # returns integer 42
```

Note that these functions will raise a `ValueError` if the string cannot be parsed to the desired type.
