How to control the output format when moving Chinese characters and ascii?

Question

I find it difficult to align the text.

'''
data=[ [cell  for cell in row.split(",") ] for row in table.split("\n")  if row]
len0=max([ len(x[0])   for x in data])
len1=max([ len(x[1])   for x in data])
len2=max([ len(x[2])   for x in data])

for cell in data:
    print("_"*((len0+len1+len2)*2+4) )
    print("|%24s|%4s|%20s|" % (cell[0],cell[1],cell[2]))

Not every line (12 + 2 + 10) * 2 + 4 character widths, the same format control statement, but different output, how can I fix it so that each line has the same output format, the same width?

Answer 1

Not beautiful, but here is one way. (encoding / decoding with bytes.rjust)

Answer 2

You can take into account the number of characters fullwidth vs halfwidth per line:

#!/usr/bin/python3
# coding=utf8

import unicodedata

def wide_chars(s):
    return sum(unicodedata.east_asian_width(x)=='W' for x in s)
def width(s):
    return len(s) + wide_chars(s)

    print("|%*s|%*s|%*s|" % (24-wide_chars(cell[0]), cell[0],
                               4-wide_chars(cell[1]),cell[1],
                               20-wide_chars(cell[2]), cell[2]))
