python - openpyxl线程安全吗？

Question

openpyxl线程安全吗？ 我希望有一个线程更改工作表，而另一个线程定期保存。我想知道我是否需要在更改和保存操作周围添加一个锁定对象，或者它是否已经内置到 openpyxl 中。我没有在文档中看到任何内容，也没有看到任何关于 openpyxl 中线程的问题。

阅读您的回答后，我进行了以下测试:

import threading 
import random 
import time 
from openpyxl import Workbook

wb = Workbook() 

class openpyxlwriting ( threading.Thread): 

    def run ( self ): 

        global wb
        ws = wb.get_active_sheet()
        c = 1 
        for a in range(100):
            for b in range(10000):
                ws.cell(column = a,row=b).value = c
                c += 1
            print "row ",a

class openpyxlsaving ( threading.Thread): 

    def run ( self ): 

        global wb

        for a in range(1000): 
            wb.save('test.xlsx')
            print "saved"

openpyxlwriting().start()
time.sleep(1)
openpyxlsaving ().start()

"OpenPyXl is thread safe; Workbooks can be created concurrently by different threads. However, each workbook should only be modified by one thread at a time."
