“”我试图同时打开多个chromedrivers/files.py。但它显示了错误。代码是从www.example.com获取示例file.py,并创建多个相同的文件,如file_1.py.然后运行所有已创建但不工作的文件。
代码是:
for proxy in file:
shutil.copyfile('/home/hp/Documents/pr/proxy_project/template.py', '/home/hp/Documents/pr/proxy_project/file_{}.py'.format(i))
file_name = "file_{}".format(i)
file_list.append(file_name)
with open('/home/hp/Documents/pr/proxy_project/file_{}.py'.format(i), 'r') as replicated_file:
data = replicated_file.readlines()
data_to_be_added = "proxy = '{}'\n".format(proxy.strip("\n"))
data[16] = data_to_be_added
with open('/home/hp/Documents/pr/proxy_project/file_{}.py'.format(i), 'w') as new_replicated_file:
new_replicated_file.writelines(data)
i += 1
for file_py in tuple(file_list):
print("File name = {}".format(file_py))
p = multiprocessing.Process(target=lambda: __import__(file_py))
p.start()
当这段代码运行时,还有另一个文件将被复制

当使用多处理时,你必须保护你的主代码,
这在多处理编程指南中有详细说明,特别是在“安全导入主模块”下。
