python - 遍历 python 列表和字符串格式

Question

在字符串格式的列表中循环一个列表

我有以下变量

BUILDING = "123"
SIDE = "ProductionA"
TODO = "traveling without moving"

我有以下列表

OS = ["Linux", "Unix", "Windows"]

我创建一个格式化的字符串列表

FLIST = [
"I am installing in {}, side {} using the {} cd".format (BUILDING,SIDE,o),
"Other random stuff",
"Even more random stuff: ".format(TODO)]

我想循环列表:

for o in OS:
    print(o)
    for f in FLIST:
        print(f)

我希望得到:

"I am installing in 123, side ProductionA using the Linux cd"
"Other random stuff",
"Even more random stuff: traveling without moving"

"I am installing in 123, side ProductionA using the Unix cd"
"Other random stuff",
"Even more random stuff: traveling without moving"

"I am installing in 123, side ProductionA using the Windows cd"
"Other random stuff",
"Even more random stuff: traveling without moving"

print(o) 有效，我正在获取值(Linux、Unix、Window)如果我在格式字符串中省略操作系统。

I am installing in {}, side {} using the {} cd".format (BUILDING,SIDE)

但是格式化列表不接受 o 变量，我得到的错误是:

NameError: name 'o' is not defined.

感谢您的帮助。

Answer 1

我已将 FLIST 放在循环内。试试看，

BUILDING = "123"
SIDE = "ProductionA"
TODO = "traveling without moving"

OS = ["Linux", "Unix", "Windows"]

for o in OS:
    print(o)
    FLIST = ["I am installing in {}, side {} using the {} cd".format (BUILDING,SIDE,o),"Other random stuff","Even more random stuff: {}".format(TODO)]
    for f in FLIST:
        print(f)

输出:

Linux
I am installing in 123, side ProductionA using the Linux cd
Other random stuff
Even more random stuff: traveling without moving
Unix
I am installing in 123, side ProductionA using the Unix cd
Other random stuff
Even more random stuff: traveling without moving
Windows
I am installing in 123, side ProductionA using the Windows cd
Other random stuff
Even more random stuff: traveling without moving
