Python - 查找所有小于a且总和大于b的连续奇数正整数对

给定两个正整数a和b ，任务是在Python编写一个程序，以找到小于第一个数字a并且它们的总和应该大于第二个数字b 的所有连续奇数对。

例子：

Input:
a = 60
b = 100
Output:
Pairs of consecutive number are:
51 , 53
53 , 55
55 , 57
57 , 59

Input:
a = 20
b = 200
Output:
None

方法：

给出两个数字，然后检查它们是否为正整数，并检查第一个数字是否大于第二个数字的一半。然后我们将检查奇数正整数并分配给变量a。在while语句中，找到并打印成对的奇数连续整数。

示例 1：

Python3

# input first and second number
a = 60
b = 100
  
print('a =', a)
print('b =', b)
  
# check the first number should be greater
# than the half of second number and both number
# should be positive integer
if(a > 0 and b > 0 and a > b/2):
  
    # to ensure value in firstNum variable
    # must be odd positive integer
    if(a % 2 == 0):
        a -= 1
    else:
        a -= 2
  
    b //= 2
    print("Pairs of consecutive number are:")
  
    # find the pairs of odd
    # consecutive positive integer
    while(b <= a):
        if(b % 2 != 0):
            x = b
            if(x + 2 <= a):
                print(x, ',', x+2)
  
        b += 1
else:
  print("None")

输出：

a = 60
b = 100
Pairs of consecutive number are:
51 , 53
53 , 55
55 , 57
57 , 59

# input first and second number
a = 20
b = 200
  
print('a =', a)
print('b =', b)
  
# check the first number should be greater
# than the half of second number and both number
# should be positive integer
if(a > 0 and b > 0 and a > b/2):
  
    # to ensure value in firstNum variable
    # must be odd positive integer
    if(a % 2 == 0):
        a -= 1
    else:
        a -= 2
  
    b //= 2
    print("Pairs of consecutive number are:")
  
    # find the pairs of odd
    # consecutive positive integer
    while(b <= a):
        if(b % 2 != 0):
            x = b
            if(x + 2 <= a):
                print(x, ',', x+2)
                 
  
        b += 1
else:
    print("None")

输出：

a = 20
b = 200
None
