Multi-line programs First, second, third
Write a program that prints the following three words in a column: first, second, third.


答案是两种 ：
人家给的提示是

solution=[print(word) for word in ['first','second','third']]

我自己写的是：

print('first','second','third',sep='\n')

Multi-line programs LinesHow many lines will this code print?

print()
print("Monday")
print("Tuesday Wednesday")
print()
print("Thursday")

注意哦，print（）输出的是一个空！！不是空格

>>> a =print()

>>> a
>>> type(a)
<class 'NoneType'>

Multi-line programs SquareWrite a program that prints this square out of * symbols.

* * * *
*     *
*     *
* * * *

Don't forget about the spaces between the asterisks!


我的答案是

print("* * * * \n*     *\n*     *\n* * * *")

还有些可以的答案是：

print("* " * 4)
print("*     *")
print("*     *")
print("* " * 4)

print('''
* * * *
*     *
*     *
* * * *
''')

[color=var(--black100)  !important]Naming variables Everest

In your program, you need a variable to store the height of mount Everest (8, 848 m). There are other heights and other mountains in the program, so you cannot simply call it height . The name of the variable should reflect the fact that the value is constant and refer to the measure and the object.

What would be an optimal name for that variable?

the_height_of_everest_in_meters
height_of_everest
everest_height
MOUNTAIN_HEIGHT
mount_everest
EVEREST_HEIGHT




最后答案的讨论认为的是，一般变量最好大写？？？

哦 ，知道 了，就是说，认为的是在不变的变量用大写upercase，比如PI圆周率
