Python安全開關文件的兩種方式

如下代碼經Python3.3測試。

一、

try:
    file = open('config.ini', 'w')
    print("It's a text file", file=file)
except IOError as err:
    print('File error: ' + str(err))
finally:
    if 'file' in locals():
        file.close()

二、

try:
    with open('config.txt', 'w') as file:
        print("It's a text file", file=file)
except IOError as err:
    print('File error: ' + str(err))
