Correct way to do 'if list in list' python -


i taught myself python little while ago , find myself continually doing piece of logic...

if element of lista in listb blah blah...

i code as:

for in lista:      if in listb:

given frequency come across assume there must more efficient way of coding this?

thanks in advance.

yes, any() function :).

if any(i in listb in lista):

this assuming want "do something" once. if want i (if in listb), use for-loop have done.

any(i in listb in lista). pretty equivalent to:

for in lista:     if in listb:         return true return false
