尝试使用pandas.read_excel
访问我的主目录时遇到了一些意外行为。
我想访问的文件可以在
找到/users/isys/orsheridanmeth
这是cd ~/
带我去的地方。我想访问的文件是
'~/workspace/data/example.xlsx'
以下内容适用于读取Excel文件(使用import pandas as pd
):
df = pd.read_excel('workspace/data/example_.xlsx', 'Sheet1')
而
df = pd.read_excel('~/workspace/data/example.xlsx', 'Sheet1')
给了我以下错误:
df = pd.read_excel('~/workspace/data/example.xlsx', 'Sheet1')
Traceback (most recent call last):

f = open(filename, "rb")
IOError: [Errno 2] No such file or directory: '~/workspace/data/example.xlsx'
pandas.read_csv 但是当我使用pd.read_csv('~/workspace/data/example.csv')
时有效。
我想继续使用这些文件的相对路径。任何解释为什么这不适用于pandas.read_excel
?
使用xlrd
使用xlrd
时出现类似错误:
import xlrd
xl = xlrd.open_workbook('~/workspace/data/example.xlsx')
Traceback (most recent call last):
File "/users/is/ahlpypi/egg_cache/i/ipython-3.2.0_1_ahl1-py2.7.egg/IPython/core/interactiveshell.py", line 3035, in run_code
exec(code_obj, self.user_global_ns, self.user_ns)
File "<ipython-input-403-90af31feff4b>", line 1, in <module>
xl = xlrd.open_workbook('~/workspace/data/example.xlsx')
File "/users/is/ahlpypi/egg_cache/x/xlrd-0.9.2-py2.7.egg/xlrd/__init__.py", line 394, in open_workbook
f = open(filename, "rb")
IOError: [Errno 2] No such file or directory: '~/workspace/data/example.xlsx'

from os.path import expanduser as ospath
df = pd.read_excel(ospath('~/workspace/data/example.xlsx'), 'Sheet1')
答案 0 :(得分:5)
我相信~
会被shell扩展 - 在这种情况下,您的代码确实会尝试打开以~
开头的路径。奇怪的是,这不起作用。 : - )
首先尝试运行os.path.expanduser()
的路径 - 这应该可以将~
变量扩展为实际值。
您可能还想查看os.path.expandvars()
。
希望有所帮助
