I am trying to loop through a folder of 70 csv files. Each of the file has 2 columns which I want to store into two arrays (xData[] and yData[]). I have attached my sample code and I am unable to print the file name and my updated arrays. Kindly help me with this code

What I have tried:

<pre>path=r"E:\Users\ConfocalUser\Documents\GitHub\qudi"
files=glob.glob(os.path.join(path,'*.csv')
xData=[]
yData=[]
for file in files:
    print(file)
    with open(path,"r") as f_in:
        reader=csv.reader(f_in)
        next(reader)
        for line in reader:
            try:
                float_1,float_2=float(line[0]),float(line[1])
                xData.append(float_1)
                yData.append(float_2)
            except ValueError:
                continue

And?
What does it do that you didn't expect, or not do that you did?
What have you tried to do to find out why?
Are there any error messages, and if so, where and when? What did you do to make them happen?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

You could start by fixing the basic syntax and other errors:

Python

import os
import glob
import csv

path=r"E:\Users\ConfocalUser\Documents\GitHub\qudi"
files=glob.glob(os.path.join(path,'*.csv')) # add the second closing parenthesis here
xData=[]
yData=[]
for file in files:
    print(file)
    with open(file,"r") as f_in: # open 'file' not 'path'
        reader=csv.reader(f_in)
        next(reader)  # NB only use this if CSV has a header line
        for line in reader:
            try:
                float_1,float_2=float(line[0]),float(line[1])
                xData.append(float_1)
                yData.append(float_2)
            except ValueError:
                continue
print('xData:', xData) # show the results
print('yData:', yData)

Always test your code first with a few simple fixed test files.
