Question

I want to write a script (generate_script.py) generating another python script (filegenerated.py)

So far i have created generate_script.py:

import os
filepath = os.getcwd()
def MakeFile(file_name):
    temp_path = filepath + file_name
    file = open(file_name, 'w')
    file.write('def print_success():')
    file.write('    print "sucesss"')
    file.close()
    print 'Execution completed.'

The file (filegenerated.py) looks now like this:

def print_success(): print “sucesss”

Now i don’t want to manually insert all linebreaks (also due to operating system difficulties)…is there a template system i can use writing python code into a python file? Does someone have an example?

Thanks a lot!

You could just use a multiline string:

import os
filepath = os.getcwd()
def MakeFile(file_name):
    temp_path = filepath + file_name
    with open(file_name, 'w') as f:
        f.write('''\
def print_success():
    print "sucesss"        
''')
    print 'Execution completed.'

If you like your template code to be indented along with the rest of your code, but dedented when written to a separate file, you could use textwrap.dedent:

import os
import textwrap

filepath = os.getcwd()
def MakeFile(file_name):
    temp_path = filepath + file_name
    with open(file_name, 'w') as f:
        f.write(textwrap.dedent('''\
            def print_success():
                print "sucesss"        
                '''))
    print 'Execution completed.'
