Question

我正在尝试编写一个程序来创建一个模拟翻转硬币的游戏。我想问用户应该扔多少次硬币。根据响应，程序应选择指定次数为0（头）或1（尾）的数字。我想要它打印这样的东西：“[头，尾，'头'，'头']：有3个头和2个尾巴”

到目前为止，这是我的代码：

import random
#this function creates a game that simulates a coin
#I will ask how many times that the coin should be tossed
def coinToss():
    number = input("How many times do you want to flip the coin?: ")
    myList = []
    counter = 0
        for element in range(number):
            flip = random.randint(0, 1)
            if flip == 0:
                myList.append("Heads")
            else:
                myList.append("Tails")


print(str(myList)) + str(":there were ") + str(counter) + str(" Heads ") + str(" and ") + str(counter) + str(" Tails")

我有我的变量计数器，但如何添加头部和尾部？非常困惑。对不起，如果这听起来很容易。我知道我的印刷品最终会出错。

Answer 1

不是将"heads"或"tails"追加到myList，而是添加数字：

for element in range(number):
    flip = random.randint(0, 1)
    myList.append(flip)

现在，当您转到打印声明时，可以使用sum()和len()：

print "There were {} heads and {} tails".format(len(myList) - sum(myList), sum(myList))

由于您的列表将包含[0, 1, 1, 0, 1, 0, 0]（示例）之类的内容，因此长度减去总和将为您提供零（头）的数量，而获得总和将为您提供数量（尾部））。

使用字符串格式更简洁：）

Answer 2

这应该对你有用

myList.count("Heads")

Answer 3

import random

def coinToss():
    numToss = input("How many times do you want to flip the coin?: ")
    tossList = []
        for element in range(number):
            flip = random.randint(0, 1)
            if flip == 0:
                tossList.append("Heads")
            else:
                tossList.append("Tails")
    print tossList, ": there were %d heads and %d tails" %(tossList.count("Heads"), tossList.count("Tails"))

或

def coinToss():
    numToss = input("How many times do you want to flip the coin?: ")
    tossList = []
    headCounter = 0
        for element in range(number):
            flip = random.randint(0, 1)
            if flip == 0:
                tossList.append("Heads")
                headCounter += 1
            else:
                tossList.append("Tails")
    print tossList, ": there were %d heads and %d tails" %(headcounter, len(tossList)-headCounter)

或

def coinToss():
    numToss = input("How many times do you want to flip the coin?: ")
    tossList = []
        for element in range(number):
            tossList.append(random.randint(0, 1))
    print tossList, ": there were %d heads and %d tails" %(tossList.count(1), tossList.count("Tails"))

或

def coinToss():
    numToss = input("How many times do you want to flip the coin?: ")
    tossList = []
        for element in range(number):
            tossList.append(random.randint(0, 1))
    print tossList, ": there were %d heads and %d tails" %(sum(tossList), tossList.count("Tails"))

或

def coinToss():
    numToss = input("How many times do you want to flip the coin?: ")
    tossList = [random.randint(0, 1) for _ in xrange(numToss)]
    print tossList, ": there were %d heads and %d tails" %(sum(tossList), tossList.count("Tails"))

或

def coinToss():
    tossList = [random.randint(0, 1) for _ in xrange(input("How many times do you want to flip the coin?: "))]
    print tossList, ": there were %d heads and %d tails" %(sum(tossList), tossList.count("Tails"))

最后打印两个不同的整数
