Python中的len()函数是什么意思

a = (1,2,3,4,5,6) #元组
b = [1,2,3,4] #列表
c = range(0,11) #range
d = {'name':'lisi','age':14} #字典
e = 'helloworld' #字符串
f = set([1,2,3,4,5]) #集合
g = frozenset([1,2,3,4,5,8]) #冻结集合
 
print(len(a))
print(len(b))
print(len(c))
print(len(d))
print(len(e))
print(len(f))
print(len(g))

>>> s = "hello Good boy doiido"
>>> len(s)
21

>>> l = ['h','e','l','l','o']
>>> len(l)
5

>>> d = {'num':123,'name':"doiido"}
>>> len(d)
2

>>> t = ('G','o','o','d')
>>> len(t)
