Python study notes [two] [original]

1. Read the configuration
#config.ini

[server]
interfaceURI = http://localhost:8080/dub/
downloadURI = http://127.0.0.1:7056/data/
saveDir = D:/temp/singlewindow/data/
agentCode = 3122263935

#config.py

import configparser

def getConfigValue(section, key):
    config = configparser.ConfigParser()
    config.read("config.ini")
    return config.get(section, key)

print(getConfigValue("server","interfaceURI "))

Second, read the file

def readfile(filename):
    f = open(filename,'r',encoding= 'utf8') # read mode
    s=f.read() # Read the entire file at once, not suitable for large files
    f.close()
    return s

3. Multithreading

from time import sleep

def downloadmessage():
    print("The download message thread starts to start...")
    while (True):
        #do download

def uploadreceipt():
    print("Upload receipt thread starts...")
    while (True):
        #do upload


if __name__ == '__main__':
    threads = []
    t1 = threading.Thread(target=downloadmessage)
    threads.append(t1)
    t2 = threading.Thread(target=uploadreceipt)
    threads.append(t2)

    for t in threads:
        t.setDaemon(True)
        t.start()

    t.join()

    print("The main thread has finished running...")

Fourth, exception handling

try:
     files = httprequest.getFileByRequests()
     arr=json.loads(files)
     for i in range(0, len(arr)):
         download.downloadFile(arr[i].get('fileName'))
except:
     print("Unexpected error:", sys.exc_info()[0])
finally:
     sleep(1)

Five, package and
install pyinstaller, see the python study notes for the installation method [1]

#Type into launcher.exe
pyinstaller -F -i c:\zjport.ico launcher.py
