如何在同一个for循环下，逐步执行命令

Question

如何在同一个for循环下，逐步执行命令（执行完上一条命令后，在执行下一条命令）

from os import listdir, remove, rename
from os.path import isdir, isfile, join
from time import sleep

dirs = [i for i in listdir('./') if isdir(join('./', i))] 查找该层文件夹下所有的文件夹，返回列表
for files in dirs:
dir = [i for i in listdir(files)]
for file in dir:
text = './' + files + '/' + file
if file == "**.txt":
with open(text, "r", encoding="utf-8") as f1, open("%s.bak" % text, "w+", encoding="utf-8") as f2:
for f in f1.readlines():
i = 'qianzhui' + '_' + f
f2.write(i)
j = f.replace("01_01", "22_02_03")
f2.write(j)
k = f.replace("01_01", "22_03_04")
f2.write(k)
l = f.replace("01_01", "22_04_05")
f2.write(l)

        remove(text)
        rename("%s.bak" % text, text)

这是代码运行后的实际结果 

这是我的预期结果

哪位DL帮忙修改一下代码，实现我的预期结果

from os import getcwd, listdir, remove, rename, mkdir
from os.path import join, abspath

re_list = []
prefix = 'qianzhui_'
rename_list = ['22_02_03', '22_03_04', '22_04_05']
path = abspath(join(getcwd(), "..")) # 返回上级目录
dirs = [i for i in listdir(path)] # 查找该层文件夹下所有的文件及文件夹，返回列表
for files in dirs: # 遍历列表
dir = [i for i in listdir(join(path, files))]
for file in dir:
text = join(path, files, file)
if file == "**.txt":
with open(text, "r", encoding="utf-8") as f1, open("%s.bak" % text, "w+", encoding="utf-8") as f2:
for f in f1.readlines():
i = prefix + f
re_list.append(i)
re_list.append(f.replace("01_01", rename_list[0]))
re_list.append(f.replace("01_01", rename_list[1]))
re_list.append(f.replace("01_01", rename_list[2]))

            for i in range(len(re_list)):
                if prefix in re_list[i]:
                    f2.write(re_list[i])
            f2.write('\n\n')

            for name in rename_list:
                for i in range(len(re_list)):
                    if name in re_list[i]:
                        f2.write(re_list[i])
                f2.write('\n\n')

        remove(text)
        rename("%s.bak" % text, text)

        with open(text, "r", encoding="utf-8") as f1:
            for f in f1.readlines():
                if 'Competitors' in f:
                    name = f.strip()
                    mkdir(join(path, files, name))
