本文實例講述了Python實現獲取前100組勾股數的方法。分享給大家供大家參考，具體如下：

本來想採用窮舉試探的方式來做這個演算法，後來發現還是有點麻煩。從網路上找來了一個求解方法如下：

當a為大於1的奇數2n 1時，b=2n^2 2n,c=2n^2 2n 1。實際上就是把a的平方數拆成兩個連續自然數。

寫程式碼如下：

#!/usr/bin/python
for n in range(1,101):
 a = 2 * n +1
 b = 2 * (n** 2) + 2 * n
 c = b + 1
 # check theresult
 if a ** 2 +b ** 2 == c ** 2:
  print("a= %d, b = %d, c = %d" %(a,b,c))

程式執行結果：

a = 3, b = 4, c = 5
a = 5, b = 12, c = 13
a = 7, b = 24, c = 25
a = 9, b = 40, c = 41
a = 11, b = 60, c = 61
a = 13, b = 84, c = 85
a = 15, b = 112, c = 113
a = 17, b = 144, c = 145
a = 19, b = 180, c = 181
a = 21, b = 220, c = 221
a = 23, b = 264, c = 265
a = 25, b = 312, c = 313
a = 27, b = 364, c = 365
a = 29, b = 420, c = 421
a = 31, b = 480, c = 481
a = 33, b = 544, c = 545
a = 35, b = 612, c = 613
a = 37, b = 684, c = 685
a = 39, b = 760, c = 761
a = 41, b = 840, c = 841
a = 43, b = 924, c = 925
a = 45, b = 1012, c = 1013
