基于if语句打印的变量带有额外字符（Python）

Question

在下面的脚本中，我试图以某种方式显示设备名称，具体取决于它是否已加入域或是否在工作组中。

大部分脚本都有效，但我在devicename变量中获得了额外的字符。

打印输出如下：

print dev_name = hostname    
print fqdn_name = hostname + domain     
print devicename = ('dev_name or fqdn_name',) - extra characters are (' ',)
print devicename should = dev_name or fqdn_name

非常感谢任何帮助。

谢谢，
