My friend told me that I should use assembly to get my code to run faster, but it's really hard to program in and I don't know where to begin. 
Are there any programs that can generate assembly from an easier language like python??
Your friend is wrong.  Most programs don't get demonstrably faster when written in assembly.  What makes assembly code fast is that assembly code programmers generally worry a lot about speed and size, and so that's the focus of their efforts.  Most compilers can do a much better job of creating fast programs than an only-average programmer can in assembly.
need an assembly code generator
