This program uses the requests library to send a POST request to the Kite API’s login endpoint. The API key and secret are stored in variables and passed in the request body as a JSON object. The response returned by the API contains the access token which is then extracted and printed. The pyotp library is used to generate a Time-based One-Time Password (TOTP) token that is used to authenticate the login request. The TOTP secret should be kept safe and not shared. The TOTP token is generated using pyotp.TOTP(TOTP_SECRET) and the current time based token is obtained by calling totp.now(). The TOTP token is included in the request data along with the API key and secret.

Please note that this is a simplified version of the login process and you may need to handle other aspects of the authentication process like handling redirects and verifying the authenticity of the response. Also replace YOUR_API_KEY, YOUR_API_SECRET and YOUR_TOTP_SECRET with your own api_key, api_secret and totp_secret respectively.
