My two bits...
Use the python interpreter a lot! Run through the examples in the tutorial, see the output piece by piece, then make small variations and see the output. For example, when the tutorial passes one variable to a function, change the variable and see the output. Then see if you can get two variables to work like you expect.
Second, when you get an output you don't expect, try and figure out why. If you can't, then utilize this great tutor list to help... I unfortunately discovered it later than necessary and ended up on using my imagination to get things to work.
Third, your English is much better than what I see everyday at my English dominant high school. I've heard that English is a hard second language, so don't critisize yourself...
