中的方框图字符问题

Question

我正在做一个终端音乐播放器。我几乎做了盒绘图界面^{货币1}$

如您所见，我打破了右边框（"║"）。我试过了。但是出了点问题，它不起作用。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)

Answer 1

Question: Issues with box drawing character using termcolor.colored symbols.

问题是从termcolor.colored返回的box1变量。
这个字符串box1已经用ANSI颜色序列格式化，例如\E231║。
因此len(trackEn)给出了6更多的结果mFactor = z - len(trackEn) == -6。
你的mFactor变为负数，因此不indent

Change the following:

    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)
