编写一个 Python 程序来打印集合中的正数或项目。 for 循环 (for posVal in PositiveSet) 中的 if 语句 (if(posVal >= 0)) 检查集合项目是否大于或等于零。如果为 True，则打印该正集合数字。
# Set Positive Numbers
PositiveSet = {7, -8, -11, 4, -85, 14, -22, 78, 11}
print("Positive Set Items = ", PositiveSet)
print("\nThe Positive Numbers in this PositiveSet Set are:")
for posVal in PositiveSet:
if(posVal >= 0):
print(posVal, end = " ")
打印集合中的正数 输出
Positive Set Items = {4, 7, -22, 11, -85, 14, 78, -11, -8}
The Positive Numbers in this PositiveSet Set are:
4 7 11 14 78 在此程序中，我们允许您输入集合项并打印集合中的正数。
# Set Positive Numbers
positiveSet = set()
number = int(input("Enter the Total Positive Set Items = "))
for i in range(1, number + 1):
value = int(input("Enter the %d Set Item = " %i))
positiveSet.add(value)
print("Positive Set Items = ", positiveSet)
print("\nThe Positive Numbers in this positiveSet Set are:")
for posVal in positiveSet:
if(posVal >= 0):
print(posVal, end = " ")
打印正集合项 输出
Enter the Total Positive Set Items = 4
Enter the 1 Set Item = -32
Enter the 2 Set Item = 23
Enter the 3 Set Item = -99
Enter the 4 Set Item = 77
Positive Set Items = {-32, 77, -99, 23}
The Positive Numbers in this positiveSet Set are:
77 23 在此 Python 集合 示例中，我们创建了一个 setPositiveNumbers 函数来查找和打印正数。
# Set Positive Numbers
def setPositiveNumbers(positiveSet):
for posVal in positiveSet:
if(posVal >= 0):
print(posVal, end = " ")
positiveSet = set()
number = int(input("Enter the Total Positive Set Items = "))
for i in range(1, number + 1):
value = int(input("Enter the %d Set Item = " %i))
positiveSet.add(value)
print("Positive Set Items = ", positiveSet)
print("\nThe Positive Numbers in this positiveSet Set are:")
setPositiveNumbers(positiveSet)
