python3 一个点球小游戏 学习random模块

设定：射门和补救只有3个方向选择“左、中、右”，补救方向电脑随机选择。

from random import choice
print("choice one side to shoot:\nleft center right")
you = input()
print("you kicked:" + you)
com = choice(["left", "center", "right"])
print("computer saved:" + com)
if you != com:
    print("goal!")
else:
    print("oops...")

choice one side to shoot:
left center right
center
you kicked:center
computer saved:right
goal!

random模块用于生成随机数

1、random.random()：随机生成一个0到1的浮点小数

2、random.uniform(a, b)：随机生成一个a到b之间的浮点小数

3、random.randint(a, b)：随机生成一个a到b之间的整数

4、random.randrange(a, b , c)：从  制定的范围a到b内    按照制定的基数递增 的集合  中获取一个随机数

5、random.choice(sequence)：从序列sequence中获取一个随机元素，sequence可以是list、tuple、字符串

6、random.shuffle(x[, random])：将一个列表中的元素打乱

7、random.sample(sequence, k)：从指定序列中随机获取指定长度的片段

random - Random variable generators.

FUNCTIONS

random(self)

     Get the next random number in the range [0.0, 1.0).

uniform(self, a, b)

     Get a random number in the range [a, b) or [a, b] depending on rounding.

randint(self, a, b)

     Return random integer in range [a, b], including both end points.

 randrange(self, start, stop=None, step=1,_int=)

     Choose a random item from range(start, stop[, step]).

choice(self,seq)

      Choose a random element from a non-empty sequence.

shuffle(self,x, random=None)

      Shuffle list x in place, and return None.

sample(self, population, k)

      Chooses k unique random elements from a population sequence or set.
