Is it possible to delete items from a list in a loop using pandas

Question

I am trying to use a list in order to append to a pandas data frame. In the process of this, I want to append the values from the list to the dataframe and then delete the values in the list, where it is then meant to repeat in a loop.

However, what it does instead is register the last pair of inputs given, there are no error values it simply does not include the other values I put in. What am I doing wrong, and do I need to do something completely different. Thanks

n = int(input("\nhow big is the sample size?:   "))
p = "q" 
num = 0
Sample1 = []

z = 1
for q in range (0, n):
    c = float(input(f"\tAdd the predictor# {z}:  ")) #z is to count the number of values for the list
    d = float(input(f"\tAdd the response# {z}:  "))
           
    if q > 0:      
        Sample1.append(c) # to append the values to the list
        Sample1.append(d)
        
        df.loc[len(df)] = Sample1  #to append to separate dataframe
        Sample1.clear() #to remove values of list to begin loop again
    z = z+1
