I'm very very new to coding and I'm having an issue importing openpyxl into my python program. I imagine the issue is due to where I have it saved on my computer.
I've downloaded other libraries (xlrd, xlwt, xlutils) before and just saved them in my: C:\Python27\ArcGIS10.1\Lib, or C:\Python27\ArcGIS10.1\Lib\site-packages, or C:\Python27\ArcGISx6410.1\Lib, or C:\Python27\ArcGISx6410.1\Lib\site-packages directories and python has been able to "see" them when i import them into a script.
I've done some trolling on the web and it looks like I may be performing the "installation" of openpyxl incorrectly. I downloaded "setuptools-5.7" in order to try to run the setup.py script contained within the openpyxl library, and so far I haven't gotten that to work out.
Since I'm so new to python, I don't really understand some of the other stuff I've been finding about how to correctly install the library, like "pip install" etc.
If anyone has any ideas about how I can install or save or locate the openpyxl library in the easiest fashion (without using other programs that I don't already have), that would be great!
Your import is probably incorrect.
It needs to be.
from openpyxl import workbook

I have a question regarding h5pyViewer to view h5 files. I tried pip install h5pyViewer but that didn't work. I checked on Google and it states that h5pyViewer does not work for older versions of Python, but that there are a few solutions on GitHub. I downloaded this with pip install git+https://github.com/Eothred/h5pyViewer.git which finally gave me a successful installation.
Yet, when I want to import the package with import h5pyViewer it gave me the following error: ModuleNotFoundError: No module named 'h5pyViewer'. However when I tried to install it again it says:
Requirement already satisfied: h5pyviewer in c:\users\celin\anaconda3\lib\site-packages (-v0.0.1.15)Note: you may need to restart the kernel to use updated packages.
Any ideas how to get out of this loop or in what other way I could access an .h5 file?
There could be so many things wrong so it's hard to say what the problem is.
The actual package import has a lowercase "v": h5pyviewer (as seen in your error message).
Your IDE/python runner may not be using your Conda environment (you can select the environment in VSCode, and if you are running a script in the terminal make sure your Conda env is enabled in that terminal)
The GitHub package might be exported from somewhere else. Try something like from Eothred import h5pyviewer.
Maybe h5pyviewer is not even supposed to be imported this way!
Overall, I don't suggest using this package, it seems like it's broken on Python 3 and not well maintained. The code in GitHub looks sketchy, and very few people use it. A good indicator is usually the number of people that star or use the package, which seems extremely low. Additionally, it doesn't even have a real readme file! It doesn't say how to use it at all. Suggest you try something else like pandas. But if you really want to go with this, you can try the above debugging steps.
I'm trying to submit a script where I tabulate a datalist.
So I go:
from tabulate import tabulate
datalist = [...]
...
print(tabulate(datalist, headers = [..., ..., ...]))
Now on my laptop, I can pip install tabulate through Powershell admin (but not through Python directly, which is another question I have: why?). This allows tabulate to be imported from my script because I guess it's in the path now.
My question is: how do I account for my TA's or prof's computer? They probably won't take the extra step to pip install tabulate.
I am supposed to submit a .zip file so I was thinking maybe I could download some file into my project folder. So I searched for the tabulate documentation and I saw downloadable files (.whl and .tar.gz) but I don't really know what to do with them.
So TLDR:
I wanna learn how to:
make the import function work in my script (straight from the script) no matter which computer it is ran in, and
use .whl or .tar.gz files to add to my project folder so that no matter what, import still works.
I know that this question has already been asked. But answers below these questions doesn't fix my problem. Here it is:
When I download some code from GitHub, it's always divided into separate files. I understand that it's important to have organized code, which is why I'd like to do the same.
However, whenever I try importing a function from a file, I always seem to get a ModuleNotFoundError error.
The file that I'm trying to import is in the same directory as the file importing the code. This also doesn't work with other code, for example, when I download code from GitHub that organizes code using separate files, it still returns the same error.
I've tried two different python installations (anaconda 3.7.3 and py 3.7.0), but still not luck. FYI I use pzyo to run my files.
Here's an example of how I import another file:
from fun import f
I have tried this as well:
import os
os.chdir("C:/Users/amau4/Desktop/test")
from fon import f
How would I go about fixing this? Thanks in advance!
I am new to python and I need to read an excel file in pyscripter. I understand that I should
import xrld
in Python and then use:
book = xlrd.open_workbook(os.path.join(file_source,file_name +".xlsx"))
to open and read the excel file.
However, I just don't understand how to install this module 'xrld'. I have looked on several websites and even on stackoverflow itself, but I just don't understand anything from the explanations that are given. I just don't understand how to install 'easy install' or 'pip' (or understand what these things are in the first place) or understand how to install anything else I need to read an excel file for. So far I installed a file called 'setuptools-36.01.1' from https://pypi.python.org/pypi/setuptools which should contain something I could use for running, but I just don't understand what to do.
I thereby must admit (and think it is clear by now) that I am a real noob when it comes to programming or computers in the first place.
Can someone please help me by explaining in plain English what exactly to do in order to read an excel file in python. I have Python 3.3.2 and use Pyscripter to run my simulation.
Your help would be really appreciated!
EasyInstall (easy_install) gives you a quick and painless way to install packages remotely by connecting other websites via HTTP.
Pip is a package management system used to install and manage software packages, such as those found in the Python Package Index. Pip is a replacement for easy_install.
Since you have installed the setuptools, easy_install will be already present in your system.
So just run easy_install pip in the command line to install pip . Then pip install xlrd for installing xlrd.
example code:
import xlrd
workbook = xlrd.open_workbook('C:/User/myaccount/Book1.xls')
worksheet = workbook.sheet_by_name('Sheet1')
print worksheet
Please go through this link-Reading Excel file using Python XLRD for sample codes for reading data from excel files in python.
Hope this helps you..
I started writing python codes two weeks ago and until now I have manipulated some excel data after converting it to txt file. Now, I want to manipulate excel data directly, so I need to install openpyxl package. However, my script will be used in many different places and computers (Note that: all of them use either OS X or a Linux distrubution) which might (probably do not) contain openpyxl package installed. I want my script to check whether this package exist, and if it does not exit, then download and install it.
For that purpose, as I searched and found that I could check the existence of the package by first importing the pip module and then pip.get_installed_distributions() method. However, I am not sure whether I am in a wrong way or not. Besides, I have no idea how to download and install openpyxl package "without leaving the script".
Would you like to help me ?
You are getting ahead of yourself by trying to solve a deployment problem when you don't have the software to deploy.
Having a script trying to manage its own deployment is generally a bad idea because it takes responsibility away from package managers.
Here is my answer to your question:
Build your software under the assumption that all packages are installed/deployed correctly. I recommend creating a virtualenv (virtual environment) on your development computer, using pip to install openpyxl and any other packages you need.
Once your software is built and functional, read up on how to deploy your software package to PyPi: https://pypi.python.org/pypi. Create your package by defining openpyxl as a dependency, ensure your package can be installed/run properly (I recommend adding in tests), then deploy to PyPi so anyone can use your software.
If you want to add a nice layer of validation in your script just in case, add the following to your main method:
#!/usr/bin/env python3
import sys
try:
import openpyxl
except ImportError as iE:
print("Python Excel module 'openpyxl' not found")
sys.exit(1)
... rest of script ...
