Question

它提示我图像中出现此错误：我想知道是否有人能够弄明白我的代码有什么问题，我将不胜感激错误：

 Unhandled exception in thread started by 0.06<function su at 0x00000000032E4620>

Traceback (most recent call last):
  File "C:\Users\Zryan\Downloads\z.py", line 6, in su
    for index in range(st,end+i):
TypeError: 'float' object cannot be interpreted as an integer

代码：

import random
import _thread
def su(st,end,i):
    global subtotal, data, locks
    locks.acquire(1,-1)
    for index in range(st,end+i):
        subtotal[i] += data[index]
    locks.release()

numth = int(100)

data = list(range(numth))

for index in range(len(data)):
    data[index] = random.randint(1,10)

wt=int(input("enter the number of working threads:"))

locks = list(range(wt))

subtotal = list(range(wt))

seg = len(data)/wt

st=0
locks= _thread.allocate_lock()
for i in range(wt):
    st= i * seg
    end = st *seg -1
    _thread.start_new_thread(su,(st,end,i))
avg = sum(subtotal)/len(data)

print(avg)

Answer 1

将seg除以len(data)（我假设您使用的是Python 3）后，wt的值可能是浮点值。这会使end成为浮点值，当您尝试将end作为参数传递给range时，会导致观察到的错误。

您需要确保end是一个整数;最简单的方法是在设置其值时简单地使用int(seg)而不是seg。

为什么会这样？
