microPython 中模块的执行函数语法无效

问：

我正在使用 micropython，并从文档中学习，但我遇到了这个错误，它可以 network.py 运行，但运行 main.py 从 thonny IDE 运行 network.py

import time 
import network 
import urequests


class netWireless:

    def setUp(ssid,password):

        wlan = network.WLAN(network.STA_IF)
        wlan.active(True)
        wlan.connect(ssid,password)

        max_wait = 10

        while max_wait > 0:
            if wlan.status() < 0 or wlan.status() >=  3:
                break
            max_wait -= 1
            print("waiting for connection...")
            time.sleep(1)
        if wlan.status() != 3:
            raise RuntimeError('network connection failed')
            return 0;
        else:
            print('connected')
            status = wlan.ifconfig()
            print('ip = ' + status[0])
            return 1;

    def getJSON(url):
            response = urequests.get(url)
            json = response.json()
            response.close()
            return json;

#working
netWireless.setUp('ssid','password')

main.py

import config
import modules.network
import modules.dateTime

#not working 
setUpStatus = netWireless.setUp('ssid','password')

壳：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "modules/network.py", line 6
SyntaxError: invalid syntax

我已经试过了： 将值以变量形式传递给函数，赋值给变量以返回
