Question

I have functions like this:

def activate_field_1():
   print 1

def activate_field_2():
   print 2

def activate_field_3():
   print 3

How do I define activate_field_[x] for x=1:10, without typing out each one of them? I’d much rather pass a parameter, of course, but for my purposes this is not possible.

Do you want to define these individually in your source file, statically? Then your best option would be to write a script to generate them.

If on the other hand you want these functions at runtime you can use a higher order function. For e.g.

>>> def make_func(value_to_print):
...     def _function():
...         print value_to_print
...     return _function
...
>>> f1 = make_func(1)
>>> f1()
1
>>> f2 = make_func(2)
>>> f2()
2

You can generate a list of these and store, again at runtime.

>>> my_functions = [make_func(i) for i in range(1, 11)]
>>> for each in my_functions:
...     each()
...
1
2
3
...
