Python之for循环

1.遍历字符串中每个字符的for循环

name="Ted"for character in name:    print(character)2. for遍历列表元素

shows=["GOT",       "You"       "Know"   ]for show in shows:    print(show)3.for遍历元组中的元素

coms=(    "World",    "always",    "sunshine")for com in coms:    print(com)4.for循环遍历字典元素

people={    "Key1":"value1",    "Key2":"value2",    "Key3":"value3"}for peo in people:    print(peo)5.使用for循环修改可变且可迭代对象中的元素

people={    "Key1":"value1",    "Key2":"value2",    "Key3":"value3"}for peo in people:    print(peo)由于访问可迭代对象中索引和元素是很常见的操作，python提供了专门的语法

tv=[    "GOT","Narcos","Vice"]for i,show in enumerate(tv):    new=tv[i]    new=new.upper()    tv[i]=newprint(tv)6.使用两个for循环获取两个不同列表中的所有字符串，然后将每个字符大写，并放入一个新的列表中

tv=[    "GOT",    "Narcos",    "Vice"]coms=[    "Arrsted Development",    "friends",    "Always Sunny"]all_shows=[]for show in tv:    show=show.upper()    all_shows.append(show)for show in coms:    show =show.upper()    all_shows.append(show)print(all_shows)
