Find the error in following code fragment

S1 = pd.Series(1, 2, 3, 4, index = range(7))  

Find the Error :

data = np.array(['a', 'b', 'c', 'd', 'e', 'f'])  
s = pd.Series(data, index = [100, 101, 102, 103, 104, 105])   
print(s[102, 103, 104] )  

Can you correct the error ?

Why does following code cause error ?

s1 = pd.Series(range(1, 15, 3), index = list('abcd'))
