Facing issues in Python to MYSQL insertion

I've tried to use couple of methods to insert data into mysql database but getting error in all:
In the first method:
sql = ('''Insert into lgemployees (EmpID,Name,Gender,DOB,Address,PhoneNumber,Email)
VALUES (%d,$s,$s,$s,$s,$d,$s)''', (eid, name, gen, dob, add, mob, email))
mycursor.execute(sql)
mycursor.commit()
Error in this approach:
'tuple' object has no attribute 'encode'
2nd method:
sql = "Insert into lgemployees (EmpID,Name,Gender,DOB,Address,PhoneNumber,Email) VALUES(?,?,?,?,?,?,?,)"
val = (eid, name, gen, dob, add, mob, email)
mycursor.execute(sql, val)
mycursor.commit()
Error in this approach :
"Not all parameters were used in the SQL statement")
mysql.connector.errors.ProgrammingError: Not all parameters were used in the SQL statement
I've troubleshooted a lot from my end but no luck. Can any one please help as where am I wrong or what else can be a good option to insert data into mysql from python.

I dont know where you error is at, but ive tested with this code and it works.
insert_tuple = (eid, name, gen, dob, add, mob, email)
sql = """INSERT INTO lgemployees (`EmpID `,
`Name`,`Gender`, `DOB`, `Address`, `PhoneNumber`, `Email`)
VALUES (%s,%s,%s,%s,%s,%s,%s)"""
mycursor = mySQLconnection.cursor()
mycursor.execute(sql, insert_tuple)
mySQLconnection.commit()
mycursor.close()
your code throws this because one of the parameters are empty or are in a format it cant read.
"Not all parameters were used in the SQL statement")
mysql.connector.errors.ProgrammingError: Not all parameters were used in the SQL statement

How can I store a string with mixed quotes in a Sqlite database using python?

I have a string with mixed quotes that is " and '. I want to store the string in a Text field in a sqlite3 database using python.
Here is the query I'm using and I have a function that executes these queries.
"""INSERT INTO SNIPPETS (CONTENT, LANGUAGE, TITLE, BACKGROUND)
VALUES("{0}" ,"{1}","{2}", "{3}")
""".format(content, language, title, background)
Something like:
with self.connection as conn:
cursor = conn.cursor()
try:
result = cursor.execute(statement)
if(insert_operation):
return cursor.lastrowid
return result.fetchall()

You don't have to make it too complicated. Python sqlite3 will take care of the quoting for you.
statement = 'INSERT INTO SNIPPETS (CONTENT, LANGUAGE, TITLE, BACKGROUND) VALUES (?, ?, ?, ?)'
cursor.execute(statement, (content, language, title, background))

Insert query with variables postgresql python

I'm trying to insert several variables in a insert query on postgres using python. I can't wrap my head around how to use the string formatting.
For example, this works fine:
cursor.execute('''CREATE TABLE %s
(id SERIAL PRIMARY KEY,
sender varchar(255) not null,
receiver varchar(255) not null,
message varchar(255))''' %username)
as does this:
cursor.execute('''INSERT INTO test (sender, receiver, message)
VALUES(%s,%s,%s)''', (sender, receiver,message))
My problem is that I want to have the table name as a variable too. I have tried:
cursor.execute('''INSERT INTO %s (sender, receiver, message)
VALUES(%s,%s,%s)''' %username, (sender, receiver, message))
I get the following error:
TypeError: not enough arguments for format string
I get that I have to change the parentheses somehow, but I don't know how.
Thanks in advance.
EDIT:
Choose a different approach from this psycopg2 which worked perfectly.

You are passing the arguments in a wrong way. The arguments passed are causing you the trouble. Use format function instead of % as it is more sophisticated and readable.
"INSERT INTO {} (sender, receiver, message) VALUES({},{},{})".format("some", "world", "world","hello")
The output of the above:
'INSERT INTO some (sender, receiver, message) VALUES(world,world,hello)'

Use the high level sql module to avoid likely mistakes:
from psycopg2 import sql
query = sql.SQL('''
insert into {} (sender, receiver, message)
values (%s, %s, %s)
''').format(sql.Identifier(username))
cursor.execute (query, (sender, receiver, message))

SQLite not accepting unique command

Python/Flask:
cur = conn.cursor()
cur.execute('CREATE TABLE IF NOT EXISTS users (email TEXT NOT NULL UNIQUE, password TEXT)')
print('Table created')
Then in another method
def create_user(email, hashedpw):
try:
cur.execute('INSERT INTO users VALUES (?, ?)', (email, hashedpw))
conn.commit()
return "works"
except:
print(str(sqlite3.Error))
return None
Even if I input the same email 10 times it still records the data in the database and doesn't give an error. I clearly set it to UNIQUE then why isnt it working?

Your syntax looks good so only explanation that comes to mind is:
You already have a table named users in your database which doesn't have the UNIQUE constraint and since you are using IF NOT EXISTS, that table remains as it is.

Python MySQLdb failing to insert

I'm trying
title = "Title here"
url = "http://www.mysite.com/url-goes-here"
cursor.execute("""INSERT INTO `videos_justicevids` (`title`, `pageurl`) VALUES (%s, %s)""",(title, url))
I'm not getting an error, but it's not inserting into the database.

You need to commit it.
connection.commit()
