我想在这里打印所有内容，但％testcase抛出错误

Question

testcase = "tc2"

lists = ["1.1.1.1",'%s.tar',"admin","admin","n",None]%testcase

for i in lists:
    cmd = ("%s") %i
    print cmd

因为％testcase而引发错误 请说明如何执行它，因为我是编程新手

Answer 1

您需要在%testcase之后直接放置'%s.tar'：

testcase = "tc2"

lists = ["1.1.1.1",'%s.tar' %testcase,"admin","admin","n",None]

for i in lists:
    cmd = ("%s") %i
    print(cmd)

输出：

1.1.1.1
tc2.tar
admin
admin
n
None
