Answer 1

# Function to print all sub strings 
def subString(s, n): 
    # Pick starting point in outer loop 
    # and lengths of different strings for 
    # a given starting point
    c=0
    for i in range(n): 
        for len in range(i+1,n+1): 
            print(s[i: len]); #prints substring
            c+=1
    print("Number of substrings:",c)

# Driver program to test above function 
s = "abcd"; 
subString(s,len(s));
