如何使用python中的pandas从csv文件读取？

Question

I'm trying to read data from a csv file in python using pandas, but I keep getting a file not found error message.

import numpy as np
import pandas as pd
from datetime import datetime
import csv
import matplotlib.pyplot as plt
import matplotlib.dates as mdates

#import experimental data
headers = ['wave', 'otti', 'sc', 'trans','wave_sol', 'sol_15am']
df = pd.read_csv('/Documents/Research/expdata.csv', names=headers, 
skiprows=[0])

Answer 1

Lets assume that Pandas cannot find the file as that is the error returned by Pandas.

Linux:

I see in your path, you have /Documents/Research/expdata.csv on a Linux/Unix system your "Documents" folder is likely located in /home/<<username>>/Documents . Linux systems will be case sensitive when it comes to file paths. So, /home/zerodf/Documents is NOT equivalent to /home/zerodf/documents .

Mac OS:

On Mac OS, I believe that would be /Users/<<username>>/Documents . Mac OS is case insensitive, but preserving .

Windows:

On Windows, that will be C:\\users\\<<username>>\\Documents . Windows systems will not be case sensitive. On Windows, C:\\zerodf\\documents is equivalent to C:\\zerodf\\Documents .

Python is going to take path's very literally. However, when it comes to interactive data science, ipython will help you with path autocompetion.
