Python中的列文本框

用户可以预先设置框中固定长度，然后打印出值，并计算与差异的空间来保存您的结构如下：

box_design_length = 10 # box design length to store character 
ones = 2 
twos = 55 
threes = 4596 
print(''' 
╔═══════════╗╔═══════════╗ 
║ Ones  ║║ {0}{1}║ 
╠═══════════╣╠═══════════╣ 
║ Twos  ║║ {2}{3}║ 
╠═══════════╣╠═══════════╣ 
║ Threes ║║ {4}{5}║ 
╚═══════════╝╚═══════════╝ 
'''.format(ones, ' '*(box_design_length-len(str(ones))), 
    twos, ' '*(box_design_length-len(str(twos))), 
    threes, ' '*(box_design_length-len(str(threes))), 
    ) 
) 

format()做字符串格式化 {0}, {1}, {2}...在format()传递的参数的数目，其支持所有版本的Python以上2.6

输出：

╔═══════════╗╔═══════════╗ 
║ Ones  ║║ 2   ║ 
╠═══════════╣╠═══════════╣ 
║ Twos  ║║ 55  ║ 
╠═══════════╣╠═══════════╣ 
║ Threes ║║ 4596  ║ 
╚═══════════╝╚═══════════╝ 

如果你知道有python formatting你可以更好的方式做到这一点，如下图所示：

from collections import OrderedDict 
values = OrderedDict([('Ones', 2), ('twos', 55), ('threes', 4596)]) # store key, value in dictionary 
# order dictionary is used to preserve order 
def box_printer(value_set, box_design_length): 
    """ 
    print values in box 
    :param value_set: dictionary of key and value to print in box 
    :param box_design_length: length of box design 
    """ 
    count = 0 # initialize count: help to identify first loop or last loop to change box design accordingly 
    for key, value in value_set.items(): 
     if count == 0: # first loop 
      print('╔{0}╗╔{0}╗'.format('═'*box_design_length)) 
     count += 1 
     print('║ {1:^{0}}║║ {2:^{0}}║'.format(box_design_length-1, key, value)) 
     if count >= len(value_set): 
      print('╚{0}╝╚{0}╝'.format('═'*box_design_length)) 
     else: 
      print('╠{0}╣╠{0}╣'.format('═'*box_design_length)) 
box_printer(values, 11) 

你会得到这个代码你的愿望输出。

如果您正在使用Python 3.6，然后f-strings将是理想的。

t = 3 
text = (f''' 
╔═══════════╗╔═══════════╗ 
║ Ones  ║║ {t} ║ 
╠═══════════╣╠═══════════╣ 
║ Twos  ║║   ║ 
╠═══════════╣╠═══════════╣ 
''') 
print(text) 

经t变量是用大括号添加并使用的文本变量时转换。
