Size of list

[Ernesto]

for line in PM_File_Handle. readlines():
PM_fields = line.split(';')

# Is there a way to get the size of PM_Fields here ?
# Something like

size = PM_fields.size( )

# I could not find this attribute in the python docs. Thanks

>>> lst = [1,2,3]

len(lst) 3 lst.__len__() 3

in genereal all objects which implements __len__
can be passed to built-in function len len <built-in function len>

just to give one example how this can be used
class X(object): .... def __len__(self):
.... print "this instance has __len__"
.... return 100
.... x=X()
len(x) this instance has __len__
100 x.__len__()

this instance has __len__
100
