For with {} and without

Question

Ive seen people use the for loop with {} and ive seen people use it without what does it change if u put it or not (the "{}" i mean)

Answer 1

without braces i believe you can only have one statement inside the loop

Answer 2

no braces (on non indentation based languages such as python) will allow you to have one statement just as hinanawi stated
take a look at this (short) article:
