在记事本中运行Python的写权限

Question

I'm using Winpython on Windows 10 and notepad++, and want to run the following Python code:

import wave, struct, math

sampleRate = 44100.0 # hertz
duration = 1.0       # seconds
frequency = 440.0    # hertz

wavef = wave.open('sound.wav','w')
wavef.setnchannels(1) # mono
wavef.setsampwidth(2) 
wavef.setframerate(sampleRate)

for i in range(int(duration * sampleRate)):
    value = int(32767.0*math.cos(frequency*math.pi*float(i)/float(sampleRate)))
    data = struct.pack('<h', value)
    wavef.writeframesraw( data )

wavef.writeframes('')
wavef.close() 

However I get the following error:

Traceback (most recent call last):
  File "C:\Users\HP\Desktop\WinPython-64bit-2.7.10.3\robin\sound\wav_00.py", line 7, in <module>
    wavef = wave.open('sound.wav','w')
  File "C:\Users\HP\Desktop\WinPython-64bit-2.7.10.3\python-2.7.10.amd64\lib\wave.py", line 513, in open
    return Wave_write(f)
  File "C:\Users\HP\Desktop\WinPython-64bit-2.7.10.3\python-2.7.10.amd64\lib\wave.py", line 308, in __init__
    f = __builtin__.open(f, 'wb')
IOError: [Errno 13] Permission denied: 'sound.wav'

I'm running the script using C:\\Users\\HP\\Desktop\\WinPython-64bit-2.7.10.3\\python-2.7.10.amd64\\python.exe -i "$(FULL_CURRENT_PATH)"

When I run the script outside of the Winpython folder with my registered Python installation it works fine, but I want to make use of packages that are installed in the Winpython version, so this solution is not adequate

Please could someone explain how to make this work?

Answer 1

Try running as administrator.

If you running from the windows command prompt:

• Right click windows button

• Select "Command Prompt(Admin)"

• Execute the script

Hope this helps
