如何使用 python 在列表中逐行插入字符串

Question

i want to run the code in every line in this string to get only the value of the driver (c,d,e) and then but them in list the string

1                C           1048576                  30 GB IFS                
2                d           1048576                  30 GB IFS  
1                e           1048576                  30 GB IFS 

i use that code but i repeat every value of (c,d,e) 3 times in the list

d[]
for line in data.split('\n')[1:]:
                    dliver = ouput2[17]
                    print('dliver',dliver)
                    dliver1 = dliver+':'
                    print(dliver1)
                    d.append(dliver1)
                    print('d',d)

note data the veritable inside it the value of string

Answer 1

In this line

for line in data.split('\n')[1:]:

you get a variable called line that you can work with. But you never do.

If I understand the question correctly, you simply want

dliver = line[17]

instead of

dliver = ouput2[17]

Answer 2

At first we create a data structure(list) named output . Then we iterate over the string. As the last step we are splitting it with spaces and newlines in the list comprehension. At the last we append the second string of the list into the output list.

output = []
for i in stringer:
    splitted = [x for x in i.split() if x != '']
    output.append(splitted[2])
