1. Enter two odd numbers n, m Be Be
Write a loop using a for statement that computes the sum of all odd numbers from n to m Be Be
Example of input and output
| enter | output | |
| Example 1 | 1,11 | 36 |
Answer code:
m, n = tuple([int(i) for i in input().split(',')])
print(sum(i for i in range(m, n + 1) if i % 2))Test Case:
2.
Input data n, use the while statement to find the sum of 1+2+3+...+n
Example of input and output
| enter | output | |
| Example 1 | 3 | 6 |
Answer code:
n=int(input())
S=0
i=1
while i<=n:
S=S+i
i=i+1
print(S)
Test Case:
3.
input data n and m
Use the while statement to calculate the sum of all data from n to m
Example of input and output
| enter | output | |
| Example 1 | 3,5 | 12 |
Answer code:
s = input()
l = s.split(',')
n = int(l[0])
m = int(l[1])
sum = 0
while n <= m:
sum = sum + n
n = n + 1
print(sum)Test Case:
4.
Input a number to determine whether it is a prime number
If yes, output "is prime", otherwise output "not prime" Be Be
Example of input and output
| enter | output | |
| Example 1 | 3 6 |
is a prime number Be not prime |
Answer code:
x = eval(input())
for i in range(2,x):
if x%2==0:
print("不是素数")
break
else:
print("是素数")
break
Test Case:
