# 分析一下,不打印说明条件不成立,所以我们可以在7哪里设置一个if判断,并跳过该次打印 # 打印跳过但是自增并不需要跳过,所以还是需要自增 count = 1 while count < 10: if count == 7: count += 1 continue print(count) count += 1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 强调:在continue之后...
Python also has many built-in functions that return a boolean value, like theisinstance()function, which can be used to determine if an object is of a certain data type: Example Check if an object is an integer or not: x =200
['Sam', 'Peter', 'Nancy', 'Alice'] class2 = ['Bob', 'David', 'June', 'Mary'] # Ask user to type in a student's name student = input("Please type the student's name here: ") # Check the student's class number if student in class1: print("Student {} is in Class 1....

1 if __name__=='__main__': 2 test() __name__ 是当前模块名,当模块被直接运行时模块名为 __main__ 。这句话的意思就是,当模块被直接运行时,代码将被运行,当模块是被导入时,代码不被运行。 更好的例子是为了代码重用。比如你现在写了一些程序,都存在单独的py文件里。有一天你突然想用1.py文件...
