Python 内置函数 len() 能够返回字符串、列表和元组中的成员数量,且在第4章4.2.3节阅读过它的帮助文档,其中明确指出:“Return the number of items in a container”。字典是 “container”,所以可以作为 len() 的参数,并返回字典中的成员数量,即键值对的数量。
for key,value in dict.items(dict_value): count += 1 print("Total Numbers of Keys: ", count) In the above code, the “for” loop iterates over the dictionary and returns keys. For each iteration in the dictionary, the count value has been incremented by “1”. ...
