Error in MySQL Syntax run on remote server using PyCharm - mysql

Question

I am fairly new to programming and I've been trying to implement this code in Python, using PyCharm. I'm running the code via a remote server, using PyCharm on my local computer. It was written by a former colleague, and has been giving a lot of encoding issues since we updated the packages like MySQL and the Python interpreter to 3.8. The MySQL version is 8.0, but this is an update. That was not the version installed originally when the code was written.
This is the full error that I am getting:
findBestMatch
*** WARNING: FoundCity[i] = {'Country': 'Austria', 'Page': 'Contact', 'Confidence': 10, 'Mentions': 1}

The code sample of the function it is trying to run is below:
def findBestMatch(FoundCity,FoundCountry,database_country):
pair_candidates = []
for i in range(0,5):
for j in range(0,5):
if len(FoundCity)>i and len(FoundCountry)>j:
city_i = FoundCity[i].get('City')
country_j = FoundCountry[j].get('Country')
if city_i != None and country_j != None:
#sql = "SELECT City,Country_CountryName,Longitude,Latitude FROM Semanticon.City where city like '{0}' and Country_CountryName like '{1}' and Population>0 order by Population desc".format(FoundCity[i]['City'].encode('utf-8'),FoundCountry[j]['Country'].encode('utf-8'))
sql = "SELECT City,Country_CountryName,Longitude,Latitude FROM Semanticon.City where city like '{0}' and Country_CountryName like '{1}' and Population>0 order by Population desc".format(
FoundCity[i]['City'], FoundCountry[j]['Country'])
try:
cursor.execute(sql)
except:
db = MySQLdb.connect(host, username, password, database, charset='utf8')
db.set_character_set("utf8")
cursor = db.cursor()
cursor.execute(sql)
resul = cursor.fetchall()
if len(resul)>0:
pair_candidates.append({"City":FoundCity[i]['City'],"Country":FoundCountry[j]['Country'],"Score":(FoundCity[i]["Confidence"]+FoundCountry[j]["Confidence"]+0.5*(FoundCity[i]["Mentions"]+FoundCountry[j]["Mentions"]))})
#return FoundCity[i]['City'],FoundCountry[j]['Country'],FoundCity[i]['Confidence']
else:
if city_i == None:
print("*** WARNING: FoundCity[i] = ", FoundCity[i])
else:
print("*** WARNING: FoundCountry[j] = ", FoundCountry[j])
I had to take the encoding out, hence the commented out 'sql' line. The encoding was causing problems and adding an extra 'b' to the string to be read from the database.
The 'WriteToDB' function that it's complaining about is below:
def WriteToDB(City,Country,ProjectId,Confidence,Location,Version,cursor,db,database_country):
sql = None
if database_country!="":
if database_country == Country:
if City != "":
#sql = "UPDATE ProjectLocation SET City='{0}',DataTrace='{1}',Confidence={2},FoundWhere='{3}' WHERE Projects_idProjects={4} and Country='{5}';".format(City," City text mined, Country from datasource",Confidence,Location,ProjectId,original_database_cntry)
sql = "UPDATE ProjectLocation SET City='%s',DataTrace='%s',Confidence='%s',FoundWhere='%s' WHERE Projects_idProjects='%s' and Country='%s';"
values = (City, " City text mined, Country from datasource", Confidence, Location, ProjectId,
original_database_cntry)
if database_country!=Country:
if Country.encode('utf-8') in database_country:
#sql = "UPDATE ProjectLocation SET City='{0}',DataTrace='{1}',Confidence={2},FoundWhere='{3}' WHERE Projects_idProjects={4} and Country='{5}';".format(
# City, " City text mined, Country from datasource", Confidence, Location, ProjectId,
#original_database_cntry)
sql = "UPDATE ProjectLocation SET City='%s',DataTrace='%s',Confidence='%s',FoundWhere='%s' WHERE Projects_idProjects='%s' and Country='%s';"
values = (City, " City text mined, Country from datasource", Confidence, Location, ProjectId,
original_database_cntry)
else:
print("Country conflict in project:"+str(ProjectId))
else:
#sql = "Insert into ProjectLocation (Type,City,Country,Projects_idProjects,Original_idProjects,IsLocationFromDataset,Confidence,FoundWhere,Version,DataTrace)" \
# "Values ('{0}','{1}','{2}',{3},{4},0,{5},'{6}','{7}','{8}')".format("Main",City,Country,ProjectId,ProjectId,Confidence,Location,Version,"Both minded from text v0.1")
sql = "Insert into ProjectLocation (Type,City,Country,Projects_idProjects,Original_idProjects,IsLocationFromDataset,Confidence,FoundWhere,Version,DataTrace)" \
"Values ('%s','%s','%s','%s',0,'%s','%s','%s','%s','%s')"
values = ("Main", City, Country, ProjectId,ProjectId, Confidence, Location, Version, "Both minded from text v0.1")
if sql!=None:
cursor.execute(sql,values)
db.commit()
I commented out the SQL queries as shown and tried to bind them instead, because it was giving a lot of encoding errors. I'm not sure how to get rid of this error and not end up with the encoding errors yet again.
Can someone help?
UPDATE to the question.
I reverted back all the sql queries, and used the queries with the encoding now (previously commented out) and I am getting 'b's in the output.
Any suggestions on how to properly encode these SQL queries so the binary encoding does not come out as b's in the output?
Here is a sample of the output:
ProjectID,ProjectName,FoundCity,FoundCountry,DatabaseCity,DatabaseCountry,Confidence,FoundWhere,Website
2542, Migrantour Country,,b'',b'',b'',10,Contact,link
3938,GeoSmartCity,,,b'',b'',10,Contact,link
