Python compile() function

Published February 15, 2022

Python compile() is used to return the Python code object, which is either an AST object, a byte string or a normal string.  The method can be used if you want to change your Python code from an AST object or string into a code object.

 

Syntax

Compile() has the following syntax:

Compile(source, name, flags=0, mode, don’t_inherit=False, optimize=-1)

Where:

• Source- source of the  byte string, normal string or AST object

• Name-  the name of the file which will be read by the code

• Mode- the mode can either be  single or eval or exec

• Flags- the default value is set to o

• Optimize- defines the optimization level of the compiler

Example

Here is an example of how compile() works

srcCode = 'x = 20\ny = 30\nmul = x * y\nprint("mul =", mul)' execCode = compile(srcCode, 'mulstring', 'exec') exec(execCode)

Output

mul = 600
