Mapping a lowest point in graph generated using python

Question

    return print_data

# main program
num_input = parse_to_int(data)
col_num = 0 # column count
for elem in num_input:
    col_num += elem
max_min_num = get_Max_and_MaxIndex_MinIndex(num_input)
row_num = max_min_num[0] - max_min_num[2] # row count

    start_num += num_input[i] # maximum height element number

# start output
print("Output:\n")
print(" " * start_num + "o" + " " * (col_num - start_num))
print(" " * (start_num - 1) + "/|\\" + " " * (col_num - start_num - 1))
print(" " * (start_num - 1) + "< >" + " " * (col_num - start_num - 1))

# prepare data for print
print_data = []

for i in range(row_num):
    print_data.append([])
    for j in range(col_num):
        print_data[i].append(" ")

for ind in range(len(num_input)):
    fill_data(ind)

# print data
for indr in range(row_num - 1, -1, -1):
    print("".join(print_data[indr]))

The above code will give this Output

In this code, a graph is generated using python without using any libraries. The Highest tip of the graph is marked.

I want to mark the lowest tip of the graph as shown in the image below. I completely have no idea about this one. which values should be changed in order to mark the lowest tip in the generated graph?

I am a newbie to stackoverflow, please comment if you need more clarity with this..

How to mark the lowest tip here Please Help me with this
