我想将熊猫数据框保存为pdf格式。
import pdfkit as pdf
config = pdf.configuration(wkhtmltopdf="C:\Program Files\wkhtmltopdin\wkhtmltopdf.exe")
pdf.from_url('http://google.com', 'out.pdf',configuration=config)
--> not working somehow even though I downloaded wkhtmltopdin on several different locations
from weasyprint import HTML
HTML(string=pd.read_csv('cor.csv').to_html()).write_pdf("report.pdf")
dlopen() failed to load a library: cairo / cairo-2 / cairo-gobject-2
--> not working : Tried several times to solve this isseue, but cannot download library
我在stackoverflow和其他网站上尝试了5个以上的软件包和方法,但无法解决。
还有更多可以尝试的软件包吗?这让我得了癌症
谢谢。

一个选择是开始:
df.to_html()
,然后使用QT如下将HTML转换为PDF:
from PyQt4.QtGui import QTextDocument, QPrinter, QApplication
import sys
app = QApplication(sys.argv)
doc = QTextDocument()
location = "c://apython//Jim//html//notes.html"
html = open(location).read()
doc.setHtml(html)
printer = QPrinter()
printer.setOutputFileName("foo.pdf")
printer.setOutputFormat(QPrinter.PdfFormat)
printer.setPageSize(QPrinter.A4)
printer.setPageMargins(15, 15, 15, 15, QPrinter.Millimeter)
doc.print_(printer)
print("done!")
我从html to pdf获得了第二段代码,并在Mac OSX上进行了测试,取得了积极的结果。

您是否考虑过绘制Matplotlib表,然后导出表图?
import matplotlib.backends.backend_pdf
import matplotlib.pyplot as plt
import pandas as pd
d = {'x{}'.format(i): range(30) for i in range(10)}
table = pd.DataFrame(d)
fig = plt.figure()
ax=fig.add_subplot(111)
cell_text = []
for row in range(len(table)):
cell_text.append(table.iloc[row])
ax.table(cellText=cell_text, colLabels=table.columns, loc='center')
ax.axis('off')
pdf = matplotlib.backends.backend_pdf.PdfPages("output.pdf")
pdf.savefig(fig)
pdf.close()
我发现这很简单,高度可定制且与操作系统无关(据我所知)。我能够在客户端的服务器上实现此功能,而无需下载任何其他软件包。
