python计算1~100的和，1~100奇数的和，1~100偶数的和，一条代码求1~100的和

sum1 = 0
for i in range(1,101):
    sum1 = sum1 + i
    i += 1
print(f"1-100之间的和是：{sum1}")

sum1 = 0
i = 1
while True:
    sum1 = sum1 + i
    if i == 100:
        break
    i += 1
print(sum1)

sum1 = 0
for i in range(1,101):
    if i % 2 == 0:
        sum1 = sum1 +i
    i += 1
print(f"1-100之间偶数的和是：{sum1}")

sum1 = 0
for i in range(1,101):
    if i % 2 != 0:
        sum1 = sum1 +i
    i += 1
print(f"1-100之间奇数的和是：{sum1}")

print(sum(range(1,101)))
