关于抛硬币实验，要求出连续正面和连续反面的次数
下面是我写的代码，能跑起来，但是连续正面和连续反面的次数总是不对，求教是什么原因？-----------------------------------------------------------------------------------------------
import random
number = int(input("请输入抛硬币的次数："))
while True:
i = 0
sum1 = 0
sum2 = 0
last = 0
c_head = 0
c_tail = 0
max_head = 0
max_tail = 0
print("开始抛硬币实验......")
while i < number:
a = random.randint(1,10)
if a % 2 == 0:
sum1 += 1
c_head += 1
if number < 100:
print("正面",end = " ")
if c_head >= max_head:
max_head = c_head
if last == 2:
c_head = 1
last = 1
if a % 2 != 0:
sum2 += 1
c_tail += 1
if number < 100:
print("反面",end = " ")
if c_tail >= max_tail:
max_tail = c_tail
if last == 1:
c_tail = 1
last = 2
i += 1
print("一共模拟了",sum1 + sum2,"次抛硬币，结果如下：","\n正面:",sum1,"\n反面:",sum2)
print("最多连续正面：",max_head,"次")
print("最多连续反面：",max_tail,"次")
number = int(input("\n请输入抛硬币的次数："))
先判断if last == 2:
c_head = 1
然后再 c_head += 1
不然明明上次是背面，你却c_head再加1，导致最后c_head最大值--》反面---》c-head增加1--》c-head以比最大值大1的数值赋值给max_head，然后你才把c_head变成1.最终导致max_head比最大值大1.
反面同理
另外你最上边的while循环没有设置break语句，导致整个代码一直循环，停住也只是因为等待你输入。最好最后设置一下break结束循环
import random
number = int(input("请输入抛硬币的次数："))
while True:
i = 0
sum1 = 0
sum2 = 0
last = 0
c_head = 0
c_tail = 0
max_head = 0
max_tail = 0
print("开始抛硬币实验......")
while i < number:
a = random.randint(1,10)
if a % 2 == 0:
if last == 2:
c_head = 1
sum1 += 1
c_head += 1
if number < 100:
print("正面",end = " ")
if c_head >= max_head:
max_head = c_head
last = 1
if a % 2 != 0:
if last == 1:
c_tail = 1
sum2 += 1
c_tail += 1
if number < 100:
print("反面",end = " ")
if c_tail >= max_tail:
max_tail = c_tail
last = 2
i += 1
print("一共模拟了",sum1 + sum2,"次抛硬币，结果如下：","\n正面:",sum1,"\n反面:",sum2)
print("最多连续正面：",max_head,"次")
print("最多连续反面：",max_tail,"次")
s=input('还继续吗（Y/N）:')
if s == 'Y':
number = int(input("\n请输入抛硬币的次数："))

# 由于正反面计数需要连续，为了避免循环中的条件判断过于复杂，
# 在循环开始前，先抛一次开个头，循环中的判断条件就单一化了。
