[英]PANDAS: Execute to_excel successfully,but no output file
When I use to_excel to generate excel file, no error occurred , but no output file available.当我使用 to_excel 生成 excel 文件时,没有发生错误,但没有可用的输出文件。 can't find anything,any file in my supposed location... And I don't know why..在我假定的位置找不到任何文件,任何文件......我不知道为什么......
import pandas as pd
import os
import xlrd
import openpyxl
pd.set_option('display.width',None)
DIR = 'E:\Process'
datapath =os.path.join(DIR, 'Data.xlsx')
formatpath = os.path.join(DIR, 'Format.xlsx')
df = pd.read_excel(datapath)
df1=pd.read_excel(formatpath)
for i in range(0, len(df)):
target = (df.iloc[i,17])
df2 = df1
df2.iat[3,3] = target
print(df2)
filename = df.iloc[i,2]
filename = str(filename) + ".xlsx"
sourcepath = os.path.join(DIR, filename)
writer = pd.ExcelWriter(sourcepath)
df2.to_excel(writer)
print(sourcepath)
Expanding on the comment:扩展评论:
Use writer.save()
after calling to_excel
.调用to_excel
后使用writer.save()
。
Alternatively you can use the with
statement as suggested in the docs: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.ExcelWriter.html或者,您可以按照文档中的建议使用with
语句: https : //pandas.pydata.org/pandas-docs/stable/reference/api/pandas.ExcelWriter.html
When I'm trying to re-run this code on my local machine, I'm running into an error with setting DIR to 'E:\\Process'
because of the escaping of "\\" for windows machines.当我尝试在我的本地机器上重新运行此代码时,我遇到了将 DIR 设置为'E:\\Process'
的错误,因为 Windows 机器转义了“\\”。 Have you tried "E:\\\\Process"
?你试过"E:\\\\Process"
吗? or try it as a raw string literal r'E:\\Process'
?或尝试将其作为原始字符串文字r'E:\\Process'
?
