python pandas 从 dataframe 生成 pdf 文件

Question

We can easily export pandas dataframe to csv file. Please find the code below:

import pandas as pd

df = pd.read_csv('/Users/ashy/Downloads/weather_data.csv');
df.to_csv('/Users/ashy/Downloads/file1.csv');

Is there an easy way to generate pdf file from dataframe. There isn't any method available to do so. What alternate methods can we use to generate file from a dataframe? Please let me know.

thanks

This method requires the reportlab library to be installed.

The below code should work:

import pandas as pd
from reportlab.lib import colors
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle

df = pd.read_csv('/Users/ashy/Downloads/weather_data.csv')

def df_to_pdf(df, filename):
    doc = SimpleDocTemplate(filename, pagesize=letter)
    elements = []
    t = Table(df.values.tolist())
    elements.append(t)
    doc.build(elements)

df_to_pdf(df, '/Users/ashy/Downloads/weather_data.pdf')
