I am thinking of reading and translating PDF and writing it out in Outlook draft.
(Use the https://www.cpi-japan.com/services/ PDF file of IELTS Reading Samples at the top of this site)
An error occurred in the following parts.
An exception has occurred: TypeError
the JSON object must be str, bytes or byte array, not NoneType
File "C:\Users\NAME\Documents\Practice\2023_01_rensyu\test7.py", line 27, in<module>
result=tr.translate(txt_list, src="en", dest="ja").text
I would appreciate your help.I created it by referring to the following site.
1. Load text data in PDF file https://python-work.com/pdf-get-text/
2.Translated by googletrans (https://plog.shinmaiblog.com/python-translator/)
3. Outlook Draft https://gist.github.com/akilab/529c6954ddbc6024a0e8e2a381126e83)

what someone did
I heard that it is an object error that cannot be used in JSON, so I thought it might be converted to a string type object.
I inserted the following before the error occurred, but an exception occurred.
txt_list=json.loads(txt_list)
TypeError
The JSON object must be str, bytes or byte array, not list
File "C:\Users\NAME\Documents\For Practice\2023_01_rensyu\test7.py", line 24, in
txt_list=json.loads(txt_list)
add
I revised it based on the comments you gave me.

Error message where the error occurred in the code above
An exception has occurred: TypeError
the JSON object must be str, bytes or byte array, not NoneType
File "C:\Users\NAME\Documents\For Practice\2023_01_rensyu\test7.py", line 33, in
result=tr.translate(txt_list, src="en", dest="ja")
In terms of content, I tried to change the content of the following article that I was referring to myself, but it didn't work.
[Python] Try using gooletrans for automatic translation.
This article specifies the text to be translated from googletrans as a single string instead of a list.
On the other hand, the source code of the question is probably intended to speed up, but it gives you a list of strings (originally a list of numbers and strings).
Initially: List of Numbers and Strings
txt_list.append([page+1,text])
changing:list of strings
txt_list.append(text)#**Only list of changes/string**
Also, in the latest stable version (3.0.0) document, the list of strings could also be specified as parameters as follows:
translate(text, dest='en', src='auto',**kwargs)
Source of questions (modifying)
tr=Translator()
result=tr.translate(txt_list, src="en", dest="ja")#** Where the error occurred**
The latest stable version (3.0.0) has a bug (specification change?) and needs to be used in the pre-release version (4.0.0-rc1) as described in the opening article and the following article.
Pre-RELEASE can avoid errors in googletrans
Also, it seems that the pre-release version (4.0.0-rc1) does not support a list of strings, and the text to be translated must be specified as a single string.
As mentioned in the opening article and the questioner's own comments, the following should be done:print(result) should be used to create data to pass to Outlook.
tr=Translator()
try:
for pagetext intxt_list:
# One page is a single string and translates it into Japanese.
result=tr.translate(pagetext, src="en", dest="ja").text
print(result)
except Exception as:
print(e)
By the way, the part where the comment says, "This time, the last line sys.exit(main()) has an exception: NameError name 'sys' is not defined" is because the corresponding import sys has not been done.
