When everyone formats code the same way, you stop noticing formatting and read the meaning. Python's official style guide is called PEP 8. The headlines:

Rule	Example
Indent with 4 spaces	(the editor does this)
`snake_case` for variables and functions	`total_price`, `load_file()`
`CapWords` for classes	`ShoppingBasket`
`UPPER_CASE` for constants	`MAX_RETRIES = 3`
Spaces around operators and after commas	`x = a + b`, `f(1, 2)`
No spaces just inside brackets	`f(x)`, not `f( x )`
Lines under about 80 to 100 characters	split long ones inside brackets
Two blank lines between top-level functions and classes
Imports at the top, one per line	`import os` then `import sys`
Compare to `None` with `is`	`if value is None:`

You don't have to memorise it. Tools called formatters (like black or ruff format) rewrite your code into this style automatically, and linters (like ruff or flake8) point out problems. Professional projects run them on every change.
