Getting TypeError when setting spreasheet column value

for product_row in worksheet.iter_rows(min_row=2,
max_row=worksheet.max_row,
min_col=1,
max_col=5, values_only=True):
test_write = worksheet.cell(product_row,5)
test_write.value = 5
Gives me this error:
Traceback (most recent call last):
File "C:\pythonProject\main.py", line 62, in <module>
test_write = worksheet.cell(product_row,5)
File "C:\pythonProject\venv\lib\site-packages\openpyxl\worksheet\worksheet.py", line 237, in cell
if row < 1 or column < 1:
TypeError: '<' not supported between instances of 'tuple' and 'int'
But when I have this:
for product_row in range(2, worksheet.max_row+1):
test_write = worksheet.cell(product_row,5)
test_write.value = 5
I do not get any error. What am I doing wrong?

PyRPlidar IndexError: index out of range

Running the example code in the pyrplidar documentation

How do I solve this? Please help

I get the typeerror while executing the following program

def get_playlist_tracks(username, playlist_id):
results = sp.user_playlist_tracks(username,playlist_id)
playlist_items = results['items']
uris = []
while results['next']:
results = sp.next(results)
playlist_items.append(results['items'])
for item in playlist_items:
track_uri = item["track"]["uri"]
uris.append(track_uri)
return uris
get_playlist_tracks('iKetu', '7h10RuUjKqfqwWibESmwy1')
print(uris)
The Output I get is

IRR calcluation : ValueError: invalid literal for float():

I am trying to calculate IRR and its giving me result in command line but whenever I am trying to pass the values as a parameter its failing with below error
Code

irr = round(numpy.irr(array), 2)*100

# return irrYearly(array)
# array = [-30000, -30000, -30000, -30000, -30000, 107180] -- if I uncomment this line its works fine
print(irrYearly(array))
elif tenure == "Monthly":

argv[2] is a string with comma separated values, but to numpy it's a string not a list of floats. You first need to convert it like so:
float_vals = [float(x) for x in argv[2].split(",")].

'NoneType' is made when I create a list and error in randrange when I haven't used it

import random
foundwords = []
wordsDict = {}
with open("text", "r") as file:
contents = file.read().replace('\n',' ')
words = contents.split(' ')
def findwords(word):
for i in range(len(words) - 1):
if words[i] == word:
if not words[i + 1] == '':
foundwords.append(words[i + 1])
return foundwords
for word in words:
wordsDict.setdefault(word, findwords(word))
# for i in range(len(words) - 1):
# findwords(words[i])
# wordsDict.setdefault(words[i], foundwords)
# del foundwords[:]
def nextword(word):
wordList = wordsDict.get(word.lower())
new = wordList[random.randint(0, len(wordList) - 1)]
return new
def assemble():
final = [words[random.randint(0, len(words))].capitalize()]
final.append(nextword(final[-1]))
print(final)
assemble()
I have tried to create a markov-chain project, however, I get the following error:
Traceback (most recent call last):

And sometimes this error:

TypeError: object of type 'NoneType' has no len()
I have no idea how to start fixing this problem. I'm only a beginner programmer, so if my code is inefficient or anything, I apologize. Also, I'm not sure if this ok to post as a question, sorry.
