Semicolon is a statement separator. So is the end of line unless you have
open parentheses, brackets, braces, or triple-quotes. So:
a=1;b=2;b=3
is the same as:
a=1
b=2
b=3
But a Pythonism you may want to adapt is:
a,b,c = 1,2,3
In practice, semicolon is rarely used in Python, since the end of line
separates statements just as well with one less byte (none vs. one :), and
multiple assignments can be done as above.
