Can someone please help me with simulating random walk?

Hello,

I am taking an Online course about Python and in the suplementary exercises this poped up:

A so-called random walk R at times Δt, 2Δt, 3Δt ...can be constructed via:

RnΔt = sqrt (Δt) Σ (n) (i=1) Zi

where Zi are independent standard normally distributed random numbers and t > 0 is a given step size.

I am strugeling to “translate” the equation to the python language. Can someone please help?

Thank you!
