Python3中带有方框图字符界面的问题

Question

我正在使用终端音乐播放器。我几乎已经完成了制图界面。 Screenshot

如您所见，我的右墙已经破了。我试图做到。但是出了点问题，这是行不通的。看看我的代码：

import vlc
import glob
import sys
from termcolor import colored, cprint
def scanfolder(directory, extension):
    sfile = glob.glob(f'{directory}*.{extension}')
    box1 = colored("║", "yellow", attrs=["bold"])
    box2 = colored("╚", "yellow", attrs=["bold"])
    box3 = colored("═", "yellow", attrs=["bold"])
    box4 = colored("╔", "yellow", attrs=["bold"])
    box5 = colored("╗", "yellow", attrs=["bold"])
    box6 = colored("╝", "yellow", attrs=["bold"])
    x = len(directory)
    y = len(extension) + 1
    z = len(max(sfile, key=len))
    z = z - x - y + 3
    box3 = box3 * z
    print(box4 + box3 + box5)
    for i, track in enumerate(sfile):
        trackEn = box1 + str(i + 1) + ". " + str(track[x:-y])
        indent = " "
        mFactor = z - len(trackEn) #z is the most long track name length, len(trackEn) is any other track's length
        indent = indent * mFactor #space * mFactor, used to align box drawing character ║, so they can make one solid wall
        print(trackEn + indent + box1) #track name + aligning spaces + ║
    print(box2 + box3 + box6)
sext = input("Choose extension: ")
sdir = input("Choose directory: ")
cprint("""

scanfolder(sdir, sext)
chooseTrack = colored("Choose track", "green", attrs=["bold"])
colon = colored(": ", "green", attrs=["bold", "blink"])
trackn = input(chooseTrack + colon)

问题：使用termcolor.colored符号的方框图字符的问题。

问题是从box1返回的termcolor.colored变量。此字符串box1已使用ANSI颜色顺序设置格式，例如\E231║。因此，len(trackEn)会给6更多，从而导致mFactor = z - len(trackEn) == -6。您的mFactor变为负数，因此no indent。

更改以下内容：

    for i, track in enumerate(sfile):
        trackEn = str(i + 1) + ". " + str(track[x:-y])

        # z is the most long track name length, len(trackEn) is any other track's length
        mFactor = z - len(trackEn)

        # space * mFactor, used to align box drawing character ║, 
        # so they can make one solid wall 
        indent = " " * mFactor 

        # ║ + track name + aligning spaces + ║
        print(box1 + trackEn + indent + box1)
