Unable to separate csv file with thousands and commas

Feb 22, 2024 pm 01:25 PM

无法用千位和逗号分隔 csv 文件

Question content

I need to read a csv file with commas along with strings and numbers, but the numbers contain commas, for example 1,260. Also, the csv file is comma delimited so I cannot read the file in the correct way. How can I separate them?

import pandas as pd
df_customer_list=pd.read_csv("customer_list 09.01.2024.csv",sep=',')
Copy after login

The file contains the following 3 lines

angel melo,[email protected],"1,260",Yes,0
michael alem,[email protected],60,Yes,0
charles ekk,[email protected],"2,220",Yes,0
Copy after login


Correct answer


I think the core problem is that your data doesn't seem to have headers, so the display of the data frame is a bit wonky.

Taking your sample data, I seem to be able to load it fine just by specifying the thousands separator and not specifying a header.

import io
import pandas

data = """
angel melo,<a href="https://www.php.cn/link/89fee0513b6668e555959f5dc23238e9" class="__cf_email__" data-cfemail="cdaca3aaa8a1a0a8a1a2f8fb8daaa0aca4a1e3aea2a0">[email&#160;protected]</a>,"1,260",yes,0
michael alem,<a href="https://www.php.cn/link/89fee0513b6668e555959f5dc23238e9" class="__cf_email__" data-cfemail="55383c363d343930393a3a153238343c397b363a38">[email&#160;protected]</a>,60,yes,0
charles ekk,<a href="https://www.php.cn/link/89fee0513b6668e555959f5dc23238e9" class="__cf_email__" data-cfemail="6a09020b18060f195f5c2a0d070b030644090507">[email&#160;protected]</a>,"2,220",yes,0
"""

df = pandas.read_csv(io.stringio(data), thousands=",", header=none)
print(df)
Copy after login

should produce:

0                      1     2    3  4
0    angel melo  <a href="https://www.php.cn/link/89fee0513b6668e555959f5dc23238e9" class="__cf_email__" data-cfemail="74151a1311181911181b4142341319151d185a171b19">[email&#160;protected]</a>  1260  Yes  0

Mathematical Modules in Python: Statistics Mathematical Modules in Python: Statistics Mar 09, 2025 am 11:40 AM

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti
