给定一个列表,打印列表的所有子列表。
Input : list = [1, 2, 3] Output : [], [1], [1, 2], [1, 2, 3], [2], [2, 3], [3]]
Step 1 : given a list. Step 2 : take one sublist which is empty initially. Step 3 : use one for loop till length of the given list. Step 4 : Run a loop from i+1 to length of the list to get all the sub arrays from i to its right. Step 5 : Slice the sub array from i to j. Step 6 : Append it to an another list to store it. Step 7 : Print it at the end.
# Python program to print all # sublist from a given list # function to generate all the sub lists def displaysublist(A): # store all the sublists B = [[ ]] # first loop for i in range(len(A) + 1): # second loop for j in range(i + 1, len(A) + 1): # slice the subarray sub = A[i:j] B.append(sub) return B # driver code A=list() n=int(input("Enter the size of the First List ::")) print("Enter the Element of First List ::") for i in range(int(n)): k=int(input("")) A.append(k) print("SUBLIST IS ::>",displaysublist(A))
输出结果
Enter the size of the First List :: 3 Enter the Element of First List :: 1 2 3 SUBLIST IS ::> [[], [1], [1, 2], [1, 2, 3], [2], [2, 3], [3]]
