我怎样才能将代码从 python 3.11 转换为 2.7

Question

我在 python 3.11 中有一些代码，我想将其转换为 python 2.7 我尝试运行我在 3.11 到 2.7 中编写的代码，但它有一些错误这是代码：

from datetime import date
from tkinter import *
import traceback
import time

with open("log.txt", "w") as log:  # logging an error if it happens
    try:
        today = date.today()  # getting date
        d4 = today.strftime("%Y")  # setting d4 only as current year

它在 python 3.11 上运行良好，但我需要它在 2.7 上运行，但我不知道如何运行它这是我在 python 2.7 上运行时遇到的错误

Answer 1

python 2.7没有f字符串，需要用字符串格式代替。

https://docs.python.org/3/tutorial/inputoutput.html#fancier-output-formatting https://docs.python.org/2.7/library/string.html#custom-string-formatting

例如

newpath = fr'{a}\June\{jun}-6-{d4}'

成为

newpath = '{a}\June\{1}-6-{2}'.format(a, jun, d4)

你可以使用更好的变量名
