parameters are of unsupported type sqlite python

Details:

This is one of the common error a beginner will be facing when he is working on Python and SQLite bridging. Below is a scenario provided for better understanding with example.

Error:

insert_data = "INSERT INTO users VALUES (?, ?, ?)"

    user = [

        {1, "Ram", "abc@123"},

        {2, "Rahim", "wel@123"},

        {3, "Raju", "pass@123"}

    ]

    cursor.executemany(insert_data, user)

When you run the above code you will get the error:

(venv) D:\python\Course_sample\source_database>python dataBase.py

parameters are of unsupported type

This is because when ever we try to insert into database from python, they data has to be a tuple.

In the above code you can see list of set which we try to insert.

Fixed:

#insert data query

    insert_data = "INSERT INTO users VALUES (?, ?, ?)"

    user = [

        (1, "Ram", "abc@123"),

        (2, "Rahim", "wel@123"),

        (3, "Raju", "pass@123")

    ]

    cursor.executemany(insert_data, user)

The above code will get executed and the data will get inserted into the database properly.

list indices must be integers or slices, not str error in python

Below is an example to elaborate the error and for an better understanding.

Eg:

shops = [{

    "name": "Anand Motors",

    "cars": [

        {

            "name":"Ferrari",

            "Price": 25000

        },

        {

            "name": "Benz",

            "price": 15000

        }

    ]}  

]

The above dictionary is referred as list, when to try to access the dictionary data using string.

name = "Anand Motors"

print(shops[name])

The above code gives error.

Solution or fix:

name = "Anand Motors"

print(next(shop for shop in shops if shop["name"] == name))

The above code will fix this error.

Error: No module named flask in python

root cause: There is no flask installation found in the directory you are currently trying to access the application.

Solution:

When you over come the above error first install flask using below command:

py -m pip install Flask
