Hi Peter
Thanks very much for your reply. I have added one more question below.
The straightforward approach is to pass a list or tuple:
def build(build_options=()):
subprocess_check_call(("make",) + build_options)
build(("flagA=true", "flagB=true"))
This looks fine - I am trying it.
I would like to display on the console the entire make command, so I have done
this:
def build(build_options=()):
make_command = 'make '.join(map(build_options))
print('Build command: ' + make_command)
subprocess.check_call(("make",)+build_options)
but I get error:
make_command = 'make '.join(map(build_options))
TypeError: map() must have at least two arguments.
What would be the correct way to concatenate and display the elements in the
tuple please?
make_command = 'make ' + ' '.join(build_options)
You don't need 'map' because you're not doing anything to the options
before concatenating them.
The string before the .join is used as a separator between the joined
strings.
