How can i draw a vector/line starting from polar coordinates (magnitude and angle) instead of rectangular coordinates (x, y) in python with matplotlib? I started learning python just a couple days ago.

Translate polar co-ordinates to cartesian co-ordinates by doing the following:
x = magnitude*cos(angle)
y = magnitude*sin(angle)
Note: Double check if you are using degrees or radians. Usually cos and sin expect radians. To translate from angle to radians, multiply by (2*pi)/360. To translate from radians to angle, multiply by 360/(2*pi).
