python 转换 csv 为txt

Question

Hello all the people out there - I am working on a project, and it requires me to convert a.csv file to a.txt file. Basically how can I change my file extension from.csv to.txt using python. I search on line and found this link https://products.aspose.com/cells/python-java/conversion/csv-to-txt/ , so I did exactly what they told me to do. I used pip install aspose-cells , and my code look something like this:

import  jpype     
import  asposecells 
jpype.startJVM() 
from asposecells.api import Workbook
workbook = Workbook("file1.csv")
workbook.Save("file1.txt")
jpype.shutdownJVM()

In this code, my.csv file is file1.csv, and I want to change the file's extension to.txt file named file1.txt. But I keep getting an error message that looks like this:

Traceback (most recent call last):
  File "c:\Users\anyuy\Documents\College_search\program\compare.py", line 32, in <module>
    jpype.startJVM() 
  File "C:\Users\anyuy\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\jpype\_core.py", line 184, in startJVM
    jvmpath = getDefaultJVMPath()
  File "C:\Users\anyuy\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\jpype\_jvmfinder.py", line 74, in getDefaultJVMPath
    return finder.get_jvm_path()
  File "C:\Users\anyuy\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\jpype\_jvmfinder.py", line 212, in get_jvm_path
    raise JVMNotFoundException("No JVM shared library file ({0}) "
jpype._jvmfinder.JVMNotFoundException: No JVM shared library file (jvm.dll) found. Try setting up the JAVA_HOME environment variable properly.

Can someone tell me what did I do wrong and how to correct it? Thanks a lot!

Heres one way to convert the file, using only the os module:

import os

def csv_to_txt(csvfile, new_filename):
    os.rename(csvfile, new_filename)

Be aware it will through an error if you set the txt file name, to the exact name your csv file has (minus the extension). For example: data.csv and data.txt wouldn't work.
