法律研究Python程序：在给定范围内查找可被7整除且是5的倍数的数字
一个数n的倍数也同时可以被n整除。如果一个数M是n的倍数，那么当我们用n除M时，余数必须为零。此外，为了在给定范围内创建数n的倍数，我们可以多次添加n并检查结果数是否在给定范围内。另一种在给定范围内生成给定数n的倍数的方法是，找到n在给定范围内的第一个倍数，然后找到与n相乘得到该倍数的数q的值。然后将q递增1，并继续用它乘以n，直到我们得到给定范围内n的所有倍数。
示例1 - 使用余数等于零的方法在给定范围内查找可被7整除且是5的倍数的数字。
算法
步骤1 - 指定范围内的最小和最大数字。
步骤2 - 从该范围内选择数字，如果该数字除以7的余数为零。打印此数字。
步骤3 - 从该范围内选择数字，如果该数字除以5的余数为零。打印此数字。
步骤4 - 还要打印同时满足步骤2和步骤3中给定规则的数字。
步骤5 - 运行程序，然后检查结果。
Python文件包含以下内容
lowNum=50
highNum=100
print("\nIn the given range from ", lowNum, " to", highNum, " :")
for item in range(lowNum, highNum):
if (item % 7 == 0):
print("This number ", item, "is divisible by 7")
print("\nIn the given range from ", lowNum, " to", highNum, " :")
for item in range(lowNum, highNum):
if (item % 5 == 0):
print("This number ", item, " is multiple of 5")
print("\nIn the given range from ", lowNum, " to", highNum, " :")
for item in range(lowNum, highNum):
if (item % 7 == 0) and (item % 5 == 0):
print("This number ", item, "is divisible by 7 and also a multiple of 5")

示例2：使用加法方法在给定范围内查找可被7整除且是5的倍数的数字。
算法
步骤1 - 指定范围内的最小和最大数字。
步骤2 - 首先确定范围内可被7整除的最小数字。不断向其添加7，直到找到该范围内最大的此类数字。打印这些数字。
步骤3 - 首先找到范围内5的倍数的最小数字。不断向其添加5，直到找到该范围内最大的此类数字。打印这些数字。
步骤4 - 通过查找两个列表中的公共元素，还要打印同时满足步骤2和步骤3中给定规则的数字。
步骤5 - 执行程序，然后验证结果。
Python文件包含以下内容
list1=[]
list2=[]
lowNum=200
highNum=300
tobeadded=7 - (lowNum % 7)
startNum= lowNum + tobeadded

示例3：使用乘法方法在给定范围内查找可被7整除且是5的倍数的数字。
算法
步骤1 - 设置范围内的最小和最大数字。
步骤2 - 首先，确定范围内可被7整除的最小数字。如果它是7的第q个倍数，则将q递增1，并继续查找7*q，直到找到该范围内最大的此类数字。打印这些数字。
步骤3 - 然后找到范围内5的倍数的最小数字。如果它是5的第q个倍数，则将q递增1，并继续查找5*q，直到找到该范围内最大的此类数字。打印这些数字。
步骤4 - 通过查找两个列表中的公共元素，还要打印同时满足步骤2和步骤3中给定规则的数字。
