On just the semicolons, tested with a bytecode disassembler:

Python does not appear to generate extra opcodes (instructions) for the semicolons, even if you use them as intended, to separate same-line statements:
print(...); print(...)

There may be a preprocessor effect (?) but I suspect it's negligible.
