python - Do you have to check if an array element exists (not null string) in Python3? -

if associative array exists in python3, waste check if element of exists rather using it?

should you:

if 'name' in array , not array['name'].startswith('something'): 

or should just:

if not array['name'].startswith('something'): 

... , python3 handle "for" you?

you can -

if not array.get('name', 'something').startswith('something'): 

get() function returns second value default if key ( name ) not found.

so in above case , return something , if key not found in dictionary, , because of .startwith() , not , complete conditional expression evaluate false , doing in op's first example .
