Trying to write a function generating M normally distributed samples of length N

I'm trying to write a function (rangNM) generating M normally distributed samples of length N and for some reason this results in a syntax error at line 4. Does anyone know what might be causing this? Thanks in advance for the help.

def rangNM(N, M):
    iseed == 0
    sample = []
    for iseed < M:
       np.random.seed(iseed)
       sample.append(np.random.normal(scale=1, loc=0, size=N))
       iseed += 1
    return(sample)

rangNM(10, 5)
