Multiple Statements on a Single Line

Multiple Statements on a Single Line
The semicolon ( ; ) allows multiple statements on a single line given that no statement starts a new code block. Here is a sample snip using the semicolon-

import sys; x = 'foo'; sys.stdout.write(x + '\n')

Multiple Statement Groups as Suites
Groups of individual statements, which make a single code block are called suites in Python. Compound or complex statements, such as if, while, def, and class require a header line and a suite.
Header lines begin the statement (with the keyword) and terminate with a colon ( : ) and are followed by one or more lines which make up the suite. For example

if expression :
suite
elif expression :
suite
else :
suite
