请看我下面的代码：

import pandas
df = pandas.read_excel('cat.xlsx')

运行后，它给了我以下错误：

Traceback (most recent call last):
  File "d:\OneDrive\??\practice.py", line 4, in <module>
    df = pandas.read_excel('cat.xlsx')
  File "D:\python\lib\site-packages\pandas\util\_decorators.py", line 296, in wrapper

我在python中使用win32.client将.xlsx和.xls文件转换为.csv.当我执行此代码时,它会给出错误.我的代码是:

def convertXLS2CSV(aFile):
    '''converts a MS Excel file to csv w/ the same name in the same directory'''

    print "------ beginning to convert XLS to CSV ------"

    try:
        import win32com.client, os
        from win32com.client import constants as c
        excel = win32com.client.Dispatch('Excel.Application')

        fileDir, fileName = os.path.split(aFile)
        nameOnly = os.path.splitext(fileName)
        newName = nameOnly[0] + ".csv"
        outCSV = os.path.join(fileDir, newName)
        workbook = excel.Workbooks.Open(aFile)
        workbook.SaveAs(outCSV, c.xlCSVMSDOS) # 24 represents xlCSVMSDOS
        workbook.Close(False)
        excel.Quit()
        del excel

        print "...Converted " + nameOnly + " to CSV"

我在读取由我无法控制的Perl脚本编写的.xls文件时遇到问题.这些文件包含单元格内的一些格式和换行符.

filename = '/home/shared/testfile.xls'
book = xlrd.open_workbook(filename)
sheet = book.sheet_by_index(0)
for rowIndex in xrange(1, sheet.nrows):
    row = sheet.row(rowIndex)

这会引发以下错误:

_locate_stream(Workbook): seen
    0  5 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
   20  4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
172480= 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 …

我想从我的python脚本中获取excelsheet中的特定单元格值.我碰到xlrd,xlwt,xlutils读模块/从excelsheet写入/.

我用hi,hello创建了myfile.xls,如何在第一列的3个单元格中创建.

示例代码: -

import xlrd

workbook = xlrd.open_workbook('myfile.xls')
worksheet = workbook.sheet_by_name('Sheet1')
num_rows = worksheet.nrows - 1
curr_row = -1
while curr_row < num_rows:
        curr_row += 1
        row = worksheet.row(curr_row)
        print row

输出: -

[text:u'hi']
[text:u'hello']
[text:u'how']

我想从excelsheet读取特定的单元格值,有人可以建议我,如果有办法做到这一点？

我是 Python 新手，有一个问题。我正在尝试使用 pandas 导入 excel 文件，并且我正在使用 VS Code。

import pandas as pd

data = pd.read_excel(r'D:\Python\user.xlsx')
print(data)

我已经安装了xlrd，但是我收到此错误：
