how to control output format when chinese characters and ascii mixed?

Question

I find that it is difficult to make the text aligned.

table=\'\'\'乘客姓名,性别,出生日期

Answer 1

You could take into account the number of fullwidth vs halfwidth characters in the string:

#!/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)

table='''乘客姓名,性别,出生日期

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

for cell in data:
    print("_"*((len0+len1+len2)*2+4) )
    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]))

Not beautiful, but here's one way. (encode/decode with bytes.rjust)

table='''乘客姓名,性别,出生日期

李红晶,女,1994/12/09

'''
table = table.encode('gb18030')
data = [[cell  for cell in row.split(b",")]

len1 = max([len(x[1]) for x in data])
