Python Syntax

Indentation defines blocks, newlines end statements, and `#` starts a comment.

Beginner

if voltage > 5:          # a colon opens a block
    print("too high")    # the block is indented (4 spaces by convention)
print("done")            # back to the outer level

One statement per line; a long expression can continue inside (), [] or {}.
Names are case-sensitive: Count and count are different.
Style is guided by PEP 8 — tools like Ruff and Black apply it automatically.
