我找到了两种方法来确定变量中有多少元素……我总是得到相同的值len ()和size ()。有区别吗？可以size ()带有导入的库（例如math, numpy, pandas）吗？

asdf = range (10)
print ( 'len:', len (asdf), 'versus size:', size (asdf) )

asdf = list (range (10))
print ( 'len:', len (asdf), 'versus size:', size (asdf) )

asdf = np.array (range (10))
print ( 'len:', len (asdf), 'versus size:', size (asdf) )

asdf = tuple (range (10))
print ( 'len:', len (asdf), 'versus size:', size (asdf) )
