[Tutor] _winreg problems enumerating

[Liam Clarke]

Hi Tim,

Change this - 

try:
while 1:
test_key = regKeys.append(_winreg.EnumValue(hkey, i))
print test_key
i += 1
except EnvironmentError:
pass

to

try:
while 1:
regKeys.append(_winreg.EnumValue(hkey, i))
print regKeys[i]
i += 1
except EnvironmentError:
pass


What this does test_key = regKeys.append(_winreg.EnumValue(hkey, i)) is 
assign to test_key any value the append may return, which is None.

Out of curiosity, you know how lists work in Python?


Regards, 


Liam Clarke
