So I've been working on a pascal triangle but I'm trying to make labels on each row that say something like Row=0, Row=1, Row=2. I'm trying to place these labels before each new row starts on the Pascal triangle. Can someone help me make it based off of this code? Thanks.

x = int(input("Enter the desired height. "))
list=[1]
for i in range(x):
    print(list)
    newlist=[]
    newlist.append(list[0])
    for i in range(len(list)-1):
        newlist.append(list[i]+list[i+1])
    newlist.append(list[-1])
    list=newlist

First of all, please avoid using names of built-in functions as variable names (in your case, list; I've changed it to l). Aside from that, placing a label as you mentioned is simply referring to the iteration of the outermost loop you have. This following code should behave as intended:

x = int(input("Enter the desired height. "))
l = [1]
for i in range(x):
    # Modified v
    print("Row", i + 1, l)
    newlist = []
    newlist.append(l[0])
    for i in range(len(l) - 1):
        newlist.append(l[i] + l[i+1])
    newlist.append(l[-1])
    l = newlist

Here's a sample run:

Enter the desired height. 4
Row 1 [1]
Row 2 [1, 1]
Row 3 [1, 2, 1]
Row 4 [1, 3, 3, 1]

Hope this helped!

Python Exercise: Print out the first n rows of Pascal's triangle , Python Exercises, Practice and Solution: Write a Python function that that prints out the first n rows of Pascal's triangle.

If you reconsider the problem from right to left, instead of left to right, it simplifies quite a bit:

rows = int(input("Enter the desired height: "))

array = []

for row in range(1, rows + 1):
    array.append(1)  # both widen the row and initialize last element

    for i in range(row - 2, 0, -1):  # fill in the row, right to left
        array[i] += array[i - 1]  # current computed from previous

    print("Row", row, array)

OUTPUT

Enter the desired height: 9
Row 1 [1]
Row 2 [1, 1]
Row 3 [1, 2, 1]
Row 4 [1, 3, 3, 1]
Row 5 [1, 4, 6, 4, 1]
Row 6 [1, 5, 10, 10, 5, 1]
Row 7 [1, 6, 15, 20, 15, 6, 1]
Row 8 [1, 7, 21, 35, 35, 21, 7, 1]
Row 9 [1, 8, 28, 56, 70, 56, 28, 8, 1]

Pascal's Triangle for Python, OK code review: import math # pascals_tri_formula = [] # don't collect in a global variable. def combination(n, r): # correct calculation of combinations, n choose k� Pascal’s triangle is a triangular array of the binomial coefficients. Write a function that takes an integer value n as input and prints first n lines of the Pascal’s triangle. Following are the first 6 rows of Pascal’s Triangle. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1

I think the code is self-explanatory. You can Visualise on it here.

def pascal_triangle(degree):
'''
Gives row and column wise enrtry for given degree
'''
Pascal_list =[[1]]   #FIrst entry Defined to start 
print(Pascal_list[0] ,'\n')
for i in range(1,degree+1): #+1 As we are starting from 1
    temp_list =[]
    for j in range(i+1):  #+1 As we are considering last element
        if(j==0):#First Element = 1
            temp_list.append(1)
            continue
        elif(j == i):#Last Element = 1
            temp_list.append(1)
            continue
        else:
            temp_list.append(Pascal_list[i-1][j]+Pascal_list[i-1][j-1]) # Addition of Upper Two Elements
    Pascal_list.append(temp_list)
    print(Pascal_list[i] ,'\n')

return Pascal_list

Input :

Pascal_Triangle = pascal_triangle(4)
print('Pascal_Triangle: ', Pascal_Triangle)

Output :

[1] 

[1, 1] 

[1, 2, 1] 

[1, 3, 3, 1] 

[1, 4, 6, 4, 1] 

Pascal_Triangle:  [[1], [1, 1], [1, 2, 1], [1, 3, 3, 1], [1, 4, 6, 4, 1]]

  • I've only been able to make the row number appear above it, even then it doesn't offer the correct output as it prints out more triangles and counts a number of full triangles instead of rows in the Pascal's Triangle.
