我试图在 Python 中完整显示一列（包含推文文本），但即使我使用 pd.set_option('display.max_colwidth', None)，输出也会以截断的形式返回。下面的代码让我显示最大宽度，但我想要的是将文件保存为具有最大列宽的输出。任何帮助表示赞赏。
def display_text_max_col_width(df, width):
with pd.option_context('display.max_colwidth', width):
print(df)
display_text_max_col_width(df["col"], 1000)
[tweets ending with ellipsis][1]
【问题讨论】：
标签： python column-width truncated
任何文本都可以被截断
MAX = 80
print(text[:MAX])
所以这样很容易。
从您的 cmets 编辑。我看不到您发布的任何图片，但这是我的建议。
如果你有一个长字符串（让我们回答这个问题的一部分）作为一些长字符串。
txt1 = """ I am trying to display a column in full (containing tweet texts) in Python, but even if I use pd.set_option('display.max_colwidth', None), the output returns as truncated. The code below lets me display the maximum width, but what I want is to save the file as output with max column width. Any help is appreciated. """
txt2 = """Thanks for your response. Indeed, I am trying to get an untruncated column, which contains text, and save it as an output file (e.g., csv) as such. The problem is, ('display.max_colwidth', None) doesn't give me untruncated text in the related column. – Kamil Yilmaz 2 days ago"""
你是说这会截断或对你不起作用，但这对我有用。
>>> with pd.option_context('display.max_colwidth', None): print(pd.DataFrame([txt1,txt2])) ...

但是我不会使用这种显示任何内容的方法。您必须通过运行行并自己格式化每个单元格来自行格式化。或者应对推文中可能包含的未经过滤的控制字符的一些古怪。
您可以使用我建议的第一种方法轻松迭代：
>>> _ = [print(line[:60]) for line in df[0]]

如果您不想遍历数据，可以使用制表来格式化数据框。
>>> from tabulate import tabulate
>>> print(tabulate(df))

或者结合使用这两种方法。但我不喜欢 Pandas 输出，因为它比它的价值更麻烦。
如果您向文件提供 fp，print 将打印到文件。
>>> with open('/tmp/text', 'w') as fp:
... [print(line[:150], file=fp) for line in df[0]]
...
[None, None]
>>> [print(line) for line in open('/tmp/text').readlines() ]
