Python-创建具有动态大小的文本边框

我正在创建一个命令行脚本,我希望有一个框

+--------+
|        |
|        |
|        |
+--------+
。。。这将永远符合它的内容。我知道如何做顶部和底部,但它让ljust和rjust正常工作。每行可能有一个字符串替换,或5个,这些字符串的len可以是0到80之间的任何值

我一直在做这样的事情:


打印“|%s |”%(my_string.ljust(80 len(my_string)))

但该死的是,这太乱了。。。这只是一个硬编码的替换。我不知道如何使它变得动态,比如说第一行有2个sub,第二行有3个sub,第三行有1个sub(所有这些都是列格式)

因此,作为一个基本示例,我需要:

+--------+
| 1      |
| 1 2 3  |
| 1 2    |
+--------+
您可以使用适用于Linux和Mac的python标准库中的模块。您也可以尝试Mac、Linux和Windows的library。 你也可以。 但对于简单对话框,您可以使用下一个代码:

def my_text_frame(string_lst, width=20):
    g_line = "+{0}+".format("-"*(width-2))
    print g_line
    for line in string_lst:
        print "| {0:<{1}} |".format(line, width-4)
    print g_line
my_text_frame("""Some text
123456 789
123""".splitlines())

对于字符串格式的宽度和精度字段,可以使用
“*”
,如中所述。以下是一个示例:

text = """\
This is
a test of the
column formatting
system.""".splitlines()

maxlen = max(len(s) for s in text)
colwidth = maxlen + 2

print '+' + '-'*colwidth + '+'
for s in text:
    print '| %-*.*s |' % (maxlen, maxlen, s)
print '+' + '-'*colwidth + '+'
印刷品:

+-------------------+
| This is           |
| a test of the     |
| column formatting |
| system.           |
+-------------------+
我是这样做的:

def bordered(text):
    lines = text.splitlines()
    width = max(len(s) for s in lines)
    res = ['┌' + '─' * width + '┐']
    for s in lines:
        res.append('│' + (s + ' ' * width)[:width] + '│')
    res.append('└' + '─' * width + '┘')
    return '\n'.join(res)

因此,首先将所有对象格式化为
text
warable,然后将其传递给
bordered()
函数。

我迟到了,但我的版本如下:

def breakLine(text, wrap=80):
    if len(text) > wrap:
        char = wrap
        while char > 0 and text[char] != ' ':
            char -= 1
        if char:
            text = [text[:char]] + breakLine(text[char + 1:], wrap)
        else:
            text = [text[:wrap - 1] + '-'] + breakLine(text[wrap - 1:], wrap)
        return text
    else:
        return [cleanLine(text)]

def cleanLine(text):
    if text[-1] == ' ':
        text = text[:-1]
    if text[0] == ' ':
        text = text[1:]
    return text

def boxPrint(text, wrap=0):
    line_style = '-'
    paragraph = text.split('\n')
    if wrap>0:
        index = 0
        while index < len(paragraph):
            paragraph[index] = cleanLine(paragraph[index])
            if len(paragraph[index]) > wrap:
                paragraph = paragraph[:index] + breakLine(paragraph[index]\
                    , wrap) + paragraph[index + 1:]
            index += 1

    length = (max([len(line) for line in paragraph]))
    print '+' + line_style * length + '+'
    for line in paragraph:
        print '|' + line + ' ' * (length - len(line)) + '|'
    print '+' + line_style * length + '+'

if __name__ == "__main__":
    text = "Some text comes here to be printed in a box!!!"
    boxPrint(text, 20)
    text = "Title:\nBody lorem ipsum something body\ncheers,"
    boxPrint(text, 20)
    boxPrint(text)
    text = "No Space:\nThisIsATextThatHasNoSpaceForWrappingWhichGetsBrokenUsingDashes"
    boxPrint(text, 20)
你可以用它来做

输出:

+------------------+

| 123456 789       |
| 123              |
+------------------+
+-----------------------+
| some words that       |
| could be dynamic but  |

+-----------------------+
from tabulate import tabulate

text = """
some words that
could be dynamic but 
are currently static
"""

table = [[text]]
output = tabulate(table, tablefmt='grid')

print(output)
+-----------------------+
