6.1 Expression statements

Expression statements are used (mostly interactively) to compute and write a value, or (usually) to call a procedure (a function that returns no meaningful result; in Python, procedures return the value None). Other uses of expression statements are allowed and occasionally useful. The syntax for an expression statement is:

expression_stmt

::=

expression_list

An expression statement evaluates the expression list (which may be a single expression).

In interactive mode, if the value is not None, it is converted to a string using the built-in repr()function and the resulting string is written to standard output (see section 6.6) on a line by itself. (Expression statements yielding None are not written, so that procedure calls do not cause any output.)
