TypeError：只能将元组（不是“str”）连接到元组

检查逗号为@MosesKoledoye说，book有：

# 1. The files and directories to be backed up are
# specified in a list.
# Example on Windows:
# source = ['"C:\\My Documents"', 'C:\\Code']     # Example on Mac OS X and Linux:
source = ['/Users/swa/notes']
# Notice we had to use double quotes inside the string # for names with spaces in it.

# 2. The backup must be stored in a
# main backup directory
# Example on Windows:
# target_dir = 'E:\\Backup'
# Example on Mac OS X and Linux:
target_dir = '/Users/swa/backup'
# Remember to change this to which folder you will be using

您的代码有：

source = [r'C:\\Documents','/home/swaroop/byte', '/home/swaroop/bin']

target_dir =r'C:\\Documents','/mnt/e/backup/'

在target_dir分配中，逗号使分配的右侧为元组。要将两个字符串连接在一起，请使用+，而不是逗号：

 target_dir =r'C:\\Documents' + '/mnt/e/backup/'

更好的是，使用单个字符串。但是，/mnt是Linux目录名，而不是Windows目录名。我怀疑你确实需要：

 target_dir = '/mnt/e/backup/'

您还将Windows路径设为原始字符串，这意味着将保留两个反斜杠。要么这样做：

'C:\\Documents'

或者这个：

r'C:\Documents'

（除非你确实想要\\）

编辑：我刚注意到你也有缩进问题：

if os.system(zip_command) == 0:
print 'Successful backup to', target
else:

应该是：

if os.system(zip_command) == 0:
    print 'Successful backup to', target
else:

最后，当你说＆＃34;我复制所有的代码＆＃34;它失败了，看看你的地方与书中所说的不同。
