編程實現(xiàn)(for和while各寫 遍):
- 求1到100之間所有數(shù)的和、平均值 辑莫。
for循環(huán)：
sum = 0
for x in range(1,101):
sum += x
print("1~100的數(shù)的和為%s" "平均值為 %.2f"% (sum,sum/100))
while循環(huán)：
sum = 0
count = 1
while count <= 100:
sum+=count
count+=1
print("1~100的數(shù)的和為%s \t平均值為 %.2f"% (sum,sum/100))
- 計算1-100之間能3整除的數(shù)的和
for循環(huán)：
count = 0
for x in range(1,101):
if x % 3 == 0:
count+=x
print(count)
while循環(huán)：

print("1~100之間能3整除的數(shù)的和為%s" % (sum))
- 計算1-100之間 能被7整除的數(shù)的和
for循環(huán)：
