magicians = [‘alice‘,‘david‘,‘carolina‘]    #练习for循环。
for magician in magicians:
     print(magician.title() + ",that was a great trick!")
print("I can‘t wait to see your next trick, " + magician.title() + ".\n")   #这是没缩进后的效果。

Chicken_soup = ‘‘‘
python根据缩进来判断代码行与前一个代码行的关系，缩进让代码整洁而结构清晰。

‘‘‘
print(Chicken_soup)

Common_mistakes = "常见的缩进错误举例:\n"
print(Common_mistakes)

#magicians = [‘alice‘,‘david‘,‘carolina‘]
#for magician in magicians:
#print(magician.title() + ",that was a great trick!")        #应缩进却没缩进，python会提醒你。

magicians = [‘alice‘,‘david‘,‘carolina‘]
for magician in magicians:
     print(magician.title() + ",that was a great trick!")
print("I can‘t wait to see your next trick, " + magician.title() + ".\n")   #这一条没有缩进，因此它只能循环结束后执行一次。
#这是一个逻辑错误。从语法上看是合法的。

#msg = "lao si ji"
#   print(msg)              #没必要的缩进。

#Traverse_the_list = [‘guanfu‘,‘xiaole‘,‘fangdong‘,‘rourou‘]
#for name in Traverse_the_list               #for语句后面的冒号告诉python，下一话是循环的第一行。这里漏掉了冒号导致语法错误。
#    print(name)
