Remove unnecessary coding patterns that add complexity without providing value. Focus on clarity and simplicity by:

1. Not using enumerate() when the index is unused: ```python

   Instead of:

   for _, item in enumerate(collection): process(item)

Use:

for item in collection: process(item)

2. Using generator expressions instead of list comprehensions when creating iterables directly:
```python
# Instead of:
return tuple([x.astype(dtype) for x in args])

# Use:
return tuple(x.astype(dtype) for x in args)

1. Following Python’s idiomatic expressions for boolean operations: ```python

   Instead of:

   if (upper == False): do_something()

Use:

if not upper: do_something() ```

These simplifications improve code readability and maintain a clean, Pythonic style that aligns with best practices.
