The complie() function in python is used to return python code object from a source like (string,AST object,byte string).
Syntax For Complie(): -
compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1)
Well the return object from the compile function in python can be called by exec() and eval() method.
Parameter : -
A source that can be used in compile function that can be normal string, a byte string, or an AST object.
- A code that can be read from a file. If it doesn't read form a file then you give a name according to you.
- Either exec,eval or signal method can be used to call a function.
- Well eval accept only a single expression.
- exec take block of code with python statement like class function.
- it contain single interactive statement.
flags (optional) and dont_inherit : - if any problem stop to compile the source then it raise flag. default value : -0
optimize (optional) - optimization level with Default value -1 for compiler.
Example Program for complie() function
Example program for compile() function in python : -
codeInString = 'a = 5\nb=6\nsum=a+b\nprint("sum =",sum)'
codeObejct = compile(codeInString, 'sumstring', 'exec')
exec(codeObejct)
OUTPUT
sum = 11
compile function in python convert the string into a python code object and then execute with exec() method
