Hello I am new to coding and I am trying to open an excel file. I've install the module for openpyxl and I know have at least somewhere because every time I type in command prompt pip install openpyxl it says it exists. But when I try to use it in my visual studio code it doesn't seem to be recognizing it. I know this is probably a rookie mistake and something super simple to fix but any help is greatly appreciated.

I was just trying to see if I could write to it but I am cautious before proceeding with my code, thank you again.
Test by creating a virtual environment,there you will be able to make better use of the versions of each library.
https://docs.python.org/es/3/tutorial/venv.html
however, I recommend that you use pandas to read your excel file. (pip install pandas)
import pandas as pd
df = pd.DataFrame(pd.read_excel(file directory)
If use the shortcut Ctrl+Shift+p in Visual studio code and Select interpreter, Then select the version of python you want to use, Then open a terminal in visual studio code and type> pip freeze into the terminal and you will be able to see if openpyxl is installed, Hope this helps.

I have installed Python 3.10.6 and Pycharm community edition.
Everything was working until I tried to use numpy.
pip3 install numpy
import numpy as np
This is the error message:
pip3 install numpy
^^^^^^^
SyntaxError: invalid syntax
I also have tried to use pip install numpy and pip2 install numpy and pip3 install numpy scipy, but same error. Reinstalling both python and pycharm didn't help.
Ah, I understand your problem more specifically now. I also use PyCharm, and this same problem happened to me. It was very frustrating, and took me lots of reading to fix it.
PyCharm and other IDEs (integrated development environment) have something called 'run configurations' attached to each file you are working on. These run configurations basically specify which directory on the hard drive the file will use to read and execute your commands. The directory will contain the libraries you need to run your code.
They use these configurations to make it easy to quickly choose which directory (and which libraries) you want a certain file to use. You must specify these configurations in PyCharm for your specific file to run using Numpy. The great thing about PyCharm is that you can actually specify libraries you want to use within the IDE itself (and bypass having to specify a computer-native directory).
Here's How
Go to PyCharm Preferences
Expand the arrow that says 'Project: (your project name)'
Click on 'Python Interpreter'
Click the small '+' symbol
Type in 'numpy' to search for the library (package)
Click install package
Now try to run your file and it should be good to go!
Note that you must do this for each package you wish to use when accessing your file, and as you advance your programming knowledge it will be necessary to learn how to specify the directory you want PyCharm to run the Python Interpreter from. Since you are only using one library though, I think this solution should be fine for the time being.
You should install numpy with that command in your bash/zsh shell.
pip3 install numpy
the python script can then import it.
to test, run pip3 install numpy
then,
python to open a python shell.
and then you'll see
>>>
Type import numpy as np and be sure it imports. It should now.
It can be maddeningly confusing when first starting out with python and trying to figure out how to download libraries. Here are a few critical things I wish I understood before starting my Python journey, as well as the answer to your question.
Python is the language, and the files that support its functionality are located on the hard drive.
Libraries (like Numpy) can be thought of almost as interpreters (note that we are not using the computer definition of 'interpreter') and are stored alongside the Python files on the hard drive. They give Python more flexibility in terms of what it is able to do by increasing what commands Python is able to understand.
Once a library is downloaded, it must be imported to your Python script before you start writing library-specific commands. Importing a library tells Python: "Hey, I'm going to be writing some commands that you haven't seen before, but here is the library with the commands and what they want you to do in a way that you understand."
'pip' is Python's installer for these libraries.
Ex) I have a csv file that I want to read. I learn that Pandas has a csv reader function:
pandas.read_csv()
If I were to type this function in a script, Python would have no idea what I meant. But if I were to download Pandas, then import it into my script, Python would understand exactly what I'm saying.
How to Download Numpy
Assuming you are on Windows, open the terminal (command prompt) and run the command:
py -m pip install numpy
If you don't already have it, the terminal should have a few lines run and should end with something like 'numpy installed successfully'.
You can check to see if you have it by running the following command in your terminal:
py -m pip list
This command provides you with a list of all the downloaded libraries. You can check among them to make sure Numpy is downloaded.
Importing Libraries
Once you've downloaded the libraries you need, you need to import them into your script (the Python file where you are writing your code) in order for it to run properly. This is accomplished using the import command. One important thing to note is that you can import libraries and assign them a nickname using the as modifier.
Ex) Back to that csv file I want to read. I don't want to type 'pandas' in front of all the Pandas commands, so when I import it into the script I abbreviate it as 'pd':
import pandas as pd
pd.read_csv()
See the difference?
TL;DR for Your Scenario
Go to the terminal, and use the py -m pip list command to check if you have Numpy downloaded. If not, run the py -m pip install numpy command. Then go to your script with your actual python code, and import numpy with the import numpy command. Common Python practice is to import numpy as np, FYI.
Hope this clears things up.
It may say that you need to upgrade pip, which is fine, and it should give you a command to run that will upgrade pip to the newest version.
I am having issues with importing the pandas library into my project on VS Code. I have pandas installed on my machine and my machine is currently running python 3.9.12. I tried changing the interpreter in my IDE from 3.10.64 to 3.9.12 but I cannot find the path to it. I was wondering if there was anything else I should try/do to help fix this issue. Thank you!
Make sure you set the path using your environment variables as shown here
Then, using pip, just simply do !pip install pandas in order to have the pandas path set correctly automatically. I understand you may have installed it manually but this may help.
I'm using VS Code on Windows and I get an error like this: Python is not installed. Please download and install Python before using the extension. But I Already Have Python 3.10.2 What Should I Do? Screenshot Of Error
you probably installed Python from windows store. Please install from python website. Make sure to mark Add Python 3.X to PATH during installation. Then reopen your VScode.
Try changing your environmental variables. I don't know exactly how to explain it in a code, try checking this out: https://www.educative.io/edpresso/how-to-add-python-to-path-variable-in-windows
download python python and select the file directory of your download when vs code gives you an error
I currently need to use pandas with Thonny, because pandas is installed locally there, but all my coding is in visual studio and i want to be able to use pandas in the editor i like. I have this error while trying to run a code for pandas.
No module named 'pandas'
File "/Users/myname/Desktop/Ambassador.py", line 1, in <module>
import pandas as pd
Even tho i have already installed it, i've made several attempts with pip, conda, i installed wheel and everything suggested.
Anyone knows why is this ?
for additional info i have a Mac
Check python version where pandas is installed and use same version to run your code
It could be cause you have installed pandas at the different virtual environment. I guess, you should try to check and change environment (⇧⌘P) in visual studio especially if you are using things like conda.
Also, check it for info about environments: https://code.visualstudio.com/docs/python/environments
So I am using the Python interpreter PyPy as it makes my code run faster. However, everytime I try to run another code of mine, I get import error: No such module found. When I do a pip install pandas/numpy, it does not help as firstly the normal Python-2.7 folder already has it. And when I direct it to be installed directly to PyPy, the installation fails when it runs the setup.py file.
Could someone suggest another way in which I could get pandas and numpy to pypy? Thanks in advance!!
P.S. I have already tried: pypy setup.py install for pandas and numpy and it results in errors as well.
I'm not sure about the status of Pandas on Windows, but it looks like it doesn't work for shallow reasons and could be fixed. You should probably open an issue in PyPy's own tracker:
https://bitbucket.org/pypy/pypy/issues/
Be sure to mention it's on Windows, and include the complete copy of everything you typed and what is output.
