def HTML_with_style(df, style=None, random_id=None):
# https://stackoverflow.com/questions/38511373/change-the-color-of-text-within-a-pandas-dataframe-html-table-python-using-style/38511805#38511805
from IPython.display import HTML
import numpy as np
import re
df_html = df.to_html()
if random_id is None:
random_id = 'id%d' % np.random.choice(np.arange(1000000))
if style is None:
style = """
<style>
table#{random_id} {{color: blue}}
</style>
""".format(random_id=random_id)
else:
new_style = []
s = re.sub(r'</?style>', '', style).strip()
for line in s.split('\n'):
line = line.strip()
if not re.match(r'^table', line):
line = re.sub(r'^', 'table ', line)
new_style.append(line)
new_style = ['<style>'] + new_style + ['</style>']
style = re.sub(r'table(#\S+)?', 'table#%s' % random_id, '\n'.join(new_style))
df_html = re.sub(r'<table', r'<table id=%s ' % random_id, df_html)
return HTML(style + df_html)
new_df = HTML_with_style(df) # df is a Pandas DataFrame
f = open("test.html", 'w')
f.write(display(new_df))
But I get 但我明白了
TypeError: write() argument must be str, not None TypeError:write()参数必须是str,而不是None
Edit: Note, I'm not using IPython/Jupyter. 编辑:注意,我没有使用IPython / Jupyter。 I'm just trying to add some CSS to my HTML file, and found that HTML_with_style
post. 我只是想在我的HTML文件中添加一些CSS,并发现HTML_with_style
帖子。 If this is the completely wrong way to go about this, please let me know. 如果这是完全错误的方法,请告诉我。
it seems like you could replace 好像你可以替换它
return HTML(style + df_html)
with 同
return style + df_html
and do the following: 并执行以下操作:
with open('/path/to/file.html', 'w') as f:
f.write(HTML_with_style(df))
But, maybe you should look into https://pandas.pydata.org/pandas-docs/stable/style.html for more complex styling. 但是,也许您应该查看https://pandas.pydata.org/pandas-docs/stable/style.html以获得更复杂的样式。
I tested your function with my correction, saved a test dataframe & it shows up as a blue table in my browser like below as i believe it should: 我用我的校正测试了你的功能,保存了一个测试数据帧,它在我的浏览器中显示为蓝色表,如下所示,我相信它应该:
