I want to write two for loops in one for loop with an if condition. How do I do this? (Python) [closed]

I want to write this code with 1 for loop and if statement........................................................................................................................................................................................................................................................................................................................................................... ........................................................................................................................................................................How do I do this?.......................................................................................................................

 nlayerH = 2.4

 lamda = 500e-9
 twopi = 2*math.pi


for i in range(0,101):      # First loop
    laythic = i
    sigmalayer = (twopi*laythic*1e-9*nlayerL)/lamda

    m1 = np.array([[math.cos(sigmalayer),(1j/nlayerL)*math.sin(sigmalayer)],
                   [(1j*nlayerL)*math.sin(sigmalayer),math.cos(sigmalayer)]])


    b = m1[0][0] + m1[0][1]*nsub
    c = m1[1][0] + m1[1][1]*nsub
    y = c/b

    print(y.real)

for k in range(0,101):    #* Second loop
    laythic = k
    sigmalayer = (twopi*laythic*1e-9*nlayerH)/lamda

    m2 = np.array([[math.cos(sigmalayer),(1j/nlayerH)*math.sin(sigmalayer)],

    c = m3[1][0] + m3[1][1]*nsub 
    y = c/b

    print(y.real)
