Python threading 如何控制线程数？

[suannva]

if name == "main": file = open("mssql.ip",'r') for ip in file.readlines(): ip = ip.strip('\n') t1 = Thread(target=content,args=(ip,)) t1.start() 写一个东西 目前是这么用的 怎么控制线程数量

[pusidun]

线程池
```
pip install threadpool
```

[BBCCBB]

```python
from multiprocessing.dummy import Pool as ThreadPool
```

concurrent.future.ThreadPoolExecutor

应该有类似 java 的线程池

from multiprocessing import Pool
from multiprocessing.dummy import Pool as ThreadPool
pool = ThreadPool()
pool = ThreadPool(4) # Sets the pool size to 4
results = pool.map(func, paras)
pool.close()
pool.join()

@hanbaobao2005 这个应该是进程池吧？
