-
def total(a=5, *numbers, **phonebook): print('a', a) for single_item in numbers: print('single_item', single_item)for first_part, second_part in phonebook.items(): print(first_part,second_part) print(total(10,1,2,3,Jack=1123,John=2231,Inge=1560))
- 字符串連接鏈表
-
delimiter = '____' mylist = ['Brazil', 'Russia', 'India', 'China'] print(delimiter.join(mylist))#Brazil____Russia____India____China
- 類變量、方法，對象變量、方法
-
class Robot:'''表示有一個帶有名字的機器人。'''#類變量population = 0__population2 = 0#雙下劃線代表私有def __init__(self, name):#對象變量self.name = nameself.__name2 = name#雙下劃線代表私有Robot.population += 1#對象方法def die(self):Robot.population -= 1#類方法，用classmethod定義 @classmethoddef how_many(self):print("We have {:d} robots.".format(self.population)) Robot("蔣凱楠").how_many()
- 代碼中有中文導致的錯誤加入下面的代碼，注意別忘了等號
