Disconnect and Map Network Drive on Windows with Python

I'm using Python version 3.3.2

1. method using subprocess.Popen



# Balon Coding, 29 November 2013
# Map network drive using subprocess.Popen
# Drive letter: Q
# Shared drive path: \\192.168.51.1\balon$
# Username: balon
# Password: coding

import subprocess 

# initialize
driveLetter = 'Q:' 
networkPath = '\\\\192.168.51.1\balon$' 
user = 'balon' 
password = 'coding'

print('map network drive using subprocess.Popen')

# Disconnect anything on drive letter Q
winCMD = 'NET USE ' + driveLetter + ' /delete'
print(winCMD)
subprocess.Popen(winCMD, stdout=subprocess.PIPE, shell=True)
 
# Connect to map network drive to letter Q
winCMD = 'NET USE ' + driveLetter + ' ' + networkPath + ' /User:' + user + ' ' + password
print(winCMD)
subprocess.Popen(winCMD, stdout=subprocess.PIPE, shell=True)



2. method using subprocess.call

# Balon Coding, 29 November 2013
# Map network drive using subprocess.call
# Drive letter: Q
# Shared drive path: \\192.168.51.1\balon$
# Username: balon
# Password: coding

import subprocess 

# initialize
driveLetter = 'Q:' 
networkPath = '\\\\192.168.51.1\balon$' 
user = 'balon' 
password = 'coding'

print('map network drive using subprocess.call')

# Disconnect anything on drive letter Q
winCMD = 'NET USE ' + driveLetter + ' /delete'
print(winCMD)
subprocess.call(winCMD, shell=True)

# Connect to map network drive to letter Q
winCMD = 'NET USE ' + driveLetter + ' ' + networkPath + ' /User:' + user + ' ' + password
print(winCMD)
subprocess.call(winCMD, shell=True)

List Available Drive Letters In Python

I'm using Python version 3.3.2

import string
from ctypes import windll

def get_drives():
    drives = []
    bitmask = windll.kernel32.GetLogicalDrives()
    for letter in string.ascii_uppercase:
        if bitmask & 1:
            drives.append(letter)
        bitmask >>= 1

    return drives

if __name__ == '__main__':
    print (get_drives())     # On my PC, this prints ['C', 'D', 'W', 'X', 'Y', 'Z']

Print 'Hello World' di Python

Pertama kali belajar di Python sudah menghadapi tantangan pertama, yakni hanya untuk memunculkan "Hello World".

>>> print "Hello World!"
     File "", line 1
       print "Hello World!"
                                 ^
SyntaxError: invalid syntax
>>>

Ternyata setelah gugel, ada yang menyatakan ini merupakan syntax yang berlaku di Python 2.x, sementara yang BalonCoding gunakan adalah Python 3.3 yang sudah menggunakan syntax print (). Sehingga untuk menjalankan print "Hello World", maka lakukan seperti berikut ini,

text = "Hello World!"
print (text)
