Python object of type long has no Len() error?

Question

so i have this python code written which basically pulls data from an excel sheet using openpyxl and then fills an online web form using selenium. I managed to get the code working when it just pulls data from column B in the sheet but when I add the other columns for it to pull the data from i get this error:

Traceback (most recent call last):
File "/Users/John/Desktop/run3.py", line 103, in <module>
main()
File "/Users/John/Desktop/run3.py", line 76, in main
first.send_keys(mrn)
File "/Library/Python/2.7/site-packages/selenium-3.13.0- 
py2.7.egg/selenium/webdriver/remote/webelement.py", line 478, in send_keys
{'text': "".join(keys_to_typing(value)),
File "/Library/Python/2.7/site-packages/selenium-3.13.0- 
py2.7.egg/selenium/webdriver/common/utils.py", line 150, in keys_to_typing
for i in range(len(val)):
TypeError: object of type 'long' has no len()

I have no idea where im going wrong or even what is producing this error. Here is the code that I have so far:

       WebDriverWait(driver, 10).until(

Answer 1

Apply str function upon passing value to the send_keys function if it's a number . Generally speaking send_keys accept string, but you provide number, that leads to the exception. Changing lines below will fix issue:

from

first.send_keys(mrn)

to

first.send_keys(str(mrn))
