Issues with sudo command

I have been trying to install packages for python and when I tried to install them manually it gives me an error and says to use sudo. So i try the sudo command but asks for a password. I assumed the the password was the same as my user login but when I try to type it in nothing happens. Specifically the terminal is not reading the input from my keyboard, except for the enter key but when I press it I get a message saying the password is wrong.
If i use sudo by itself it asks for a password but the terminal won't read the keyboard.
If i use sudo followed by whatever file/command i need it gives a paragraph saying that I am not an administrator when I am.

Why is sudo not working for me?
