Python 程序：檢查數字是不是 Pronic 數字

編寫一個 Python 程序來檢查一個數字是不是 Pronic 數字，或者是否使用 while 循環。例如，如果一個數等於兩個連續數的乘積，則它是一個 Pronic 數，這意味着 number = n(n + 1)。

在這個 Python 程序中，I 值從零迭代到該數字的平方根，並檢查任意兩個連續數字的乘積是否等於實際數字。如果為真，標誌值變為 1，break 語句將退出循環。如果標誌等於 1，則它是一個 Pronic 數。

import math

Number = int(input("Enter the Number to Check Pronic Number = "))

i = 0
flag = 0

while i <= (int) (math.sqrt(Number)):
    if Number == i * (i + 1):
        flag = 1
        break
    i = i + 1

if flag == 1:
    print("\n%d is a Pronic Number." %Number)
else:
    print("%d is Not a Pronic Number." %Number)

Python 程序，使用 for 循環檢查給定的數字是否是 Pronic 數字。

Number = int(input("Enter the Number to Check Pronic Number = "))

flag = 0

for i in range(Number + 1):
    if Number == i * (i + 1):
        flag = 1
        break

if flag == 1:
    print("\n%d is a Pronic Number." %Number)
else:
    print("%d is Not a Pronic Number." %Number)

Enter the Number to Check Pronic Number = 42

42 is a Pronic Number.

Enter the Number to Check Pronic Number = 55
55 is Not a Pronic Number.

Python 程序查找一個數字是不是 Pronic 數或者不使用函數。

def pronicNumber(Number):
    flag = 0
    for i in range(Number + 1):
        if Number == i * (i + 1):
            flag = 1
            break
    return flag

Number = int(input("Enter the Number to Check Pronic Number = "))

if pronicNumber(Number) == 1:
    print("\n%d is a Pronic Number." %Number)
else:
    print("%d is Not a Pronic Number." %Number)

Enter the Number to Check Pronic Number = 52
52 is Not a Pronic Number.

Enter the Number to Check Pronic Number = 72

72 is a Pronic Number.
