Inserting python variables into Sqlite database - sqlite

Question

I am sorting out an error for my database so I have tried to isolate the problem. This function is the problem but more specifically the c.execute("INSERT INTO details VALUES(?, ?)",(e ,cp ,)).
This causes this error:
c.execute("INSERT INTO details VALUES(?, ?)",(e ,cp ,))
sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type.
I'll put the rest of the function underneath:
import sqlite3
def echecker():
email = False
password = False
right = 0
e = "the#test.com"
p = "test"
cp = "test"
space = 0
conn = sqlite3.connect("U+P.db")
c = conn.cursor()
c.execute("""SELECT email FROM details""")
data = c.fetchall()
conn.commit()
index = 0
for row in data:
if row[index] == e:
right = right + 1
else:
print("right")
print()
e = list(e)
print(e)
while space < len(e) and right == 0 and email == False:
if e[0] == "#" and e[space] == "#":
space = space + 1
print("wrong")
elif e[space] == "#":
email = True
print("right")
else:
space = space + 1
print("wrong")
print()
if p == cp:
password = True
print("right")
print()
if password == True and email == True and right == 0:
conn = sqlite3.connect("U+P.db")
print("a")
c = conn.cursor()
print("a")
c.execute("INSERT INTO details VALUES(?, ?)",(e ,cp ,))
print("a")
conn.commit()
print("siuu")
echecker()

Well, you reassign e to a list e = list(e). Of course the subsequent attempt to supply e as a query parameter will fail.
