It's hard to understand what you are trying to do here. I don't
remember just now what .config() will return, but the lambda will return
a tuple of *something*, probably (None, None, None). Even if the tuple
does contain three non-None values, config() requires named parameters,
not a tuple. In the course of executing the lambda, your three controls
e1, e2, and e2 will get configured, but you could just write a function
to do that:
def set_entries_enabled_state(enabled = True):
state = 'normal' if enabled else 'disabled'
for e in (e1, e2, e3):
e.config(state=state)
def config_b_and_entries(enabled = True):
state = 'normal' if enabled else 'disabled'
b.config(state = state)
set_entries_enabled_state(enabled)
This is easy to read and understand. (I may not have remembered some Tk
details correctly).
