### ▶ Exceeds the limit for integer string conversion
|
||||
```py
|
||||
>>> # Python 3.10.6
|
||||
>>> int("2" * 5432)
|
||||
|
||||
>>> # Python 3.10.8
|
||||
>>> int("2" * 5432)
|
||||
```
|
||||
|

**Output:**

Traceback (most recent call last):

ValueError: Exceeds the limit (4300) for integer string conversion:
|
||||
value has 5432 digits; use sys.set_int_max_str_digits()
|
||||
to increase the limit.
|
||||
```
|
||||
|
||||
#### 💡 Explanation:
|
||||
This call to `int()` works fine in Python 3.10.6 and raises a ValueError in Python 3.10.8. Note that Python can still work with large integers. The error is only raised when converting between integers and strings.
|
||||
|
||||
Fortunately, you can increase the limit for the allowed number of digits when you expect an operation to exceed it. To do this, you can use one of the following:
|
||||
- The -X int_max_str_digits command-line flag
|
||||
- The set_int_max_str_digits() function from the sys module
|
||||
- The PYTHONINTMAXSTRDIGITS environment variable
|
||||
|
||||
[Check the documentation](https://docs.python.org/3/library/stdtypes.html#int-max-str-digits) for more details on changing the default limit if you expect your code to exceed this value.
