Python: Reading multiple CSV files, and assigning each to a different variable

it fixes the issue Use a dictionary for a variable number of variables
It's poor practice to name linked variables explicitly. In this case, you can use a dictionary with enumerate:
code :
dfs = {}
for idx, f in enumerate(glob.iglob('*.csv'), 1):
    dfs[idx] = pd.read_csv(f, low_memory=False)
files = enumerate(glob.iglob('*.csv'), 1)
dfs = {idx: pd.read_csv(f, low_memory=False) for idx, f in files}

Any of those help I have a ECC key value in a text file, a set of lines I want to assign that value to a variable for further use. Though I can read the key value from the file, I have no idea as how to assign the value to a variable. I dont want it as an array. for example,
code :
# Get the data from the file
with open('public.txt') as fp:
  v = fp.read()

# The data is base64 encoded. Let's decode it.
v = v.decode('base64')

#  The data is now a string in base-256. Let's convert it to a number
v = v.encode('hex')
v = int(v, 16)

# Now it is a number. I wonder what number it is:
print v
print hex(v)
#!/usr/bin/python3

import codecs

# Get the data from the file
with open('public.txt', 'rb') as fp:
  v = fp.read()

# The data is base64 encoded. Let's decode it.
v = codecs.decode(v,'base64')

#  The data is now a string in base-256. Let's convert it to a number
v = codecs.encode(v, 'hex')
v = int(v, 16)

# Now it is a number. I wonder what number it is:
print (v)
print (hex(v))

Does that help The file appears to contain the required token on the first line, so open it with open(), and read the first line into a variable:
code :
with open('somefile.txt') as f:
    ttk = next(f).replace('Mid-access token:', '').strip()
ttk = None
with open('somefile.txt') as f:
    for line in f:
        if line.startswith('Mid-access token:'):
            ttk = next(f).strip()

print(ttk)

it fixes the issue Usually when you have a lot of data items of the same type, it's advisable to use a list or similar container. I'd do:
code :
file_number = 1
files = []
while file_number <= 100:
    file_name = 'C:/file%04d.csv' % file_number
    files.append(read_csv(file_name))
    file_number += 1

files[0].head()

will be helpful for those in need Use glob to get all files in the folder then use for loop and append the output to the variable.
code :
import glob
text = ''
for file in glob.glob('folder_name/*.docx'):
    text += docx2txt.process(file)

To fix the issue you can do From the pandas.read_csv documentation:
code :
pd.read_csv(filename, names=['firstColName', 'secondColName'], header=None)
