Python compile() Function
Python compile() Function
The compile() function takes source code as input and returns the specified source as a code object which can later be executed by exec() function.
Syntax:compile(source, filename, mode, flag, dont_inherit, optimize)
Parameter Values
| Parameter | Description |
|---|---|
| source | It is Required Parameter. The source to compile, a normal String, a byte string, or an AST (Abstract Syntax trees) object |
| filename | It is Required Parameter. The name of the file from which the code is read. |
| mode |
It is Required Parameter. Legal values: eval – In case the source is a single expression exec – In case the source is a block of statements single – In case the source is a single interactive statement |
| flags | It is Optional parameter. It monitors that how to compile the source. Default value is 0 |
| dont-inherit | It is Optional parameter. It monitors that how to compile the source. Default value is 0 |
| optimize | It is Optional parameter. It defines the optimization level of the compiler and its default value is -1 |
z = compile('print(85)', 'test', 'eval')
exec(z)
Output:
85
Example 2:
85
Sourcecode = 'a = 15\nb = 25\nmul = a * b\nprint("mul =", mul)'
execCode = compile(Sourcecode, 'mulstring', 'exec')
exec(execCode)
Output:
mul = 375
mul = 375
