今天我们来输出1~100之间的一些数学信息。
本次我们不需要任何第三方库。
输出1~100所有数字的和
sumNumber = 0 for i in range(1,101): sumNumber += i print('1~100之间所有数字之和是：',
sumNumber)
或者使用sum计算和方法：
print('1~100之间所有数字之和是：',sum(range(1,101)))
输出1~100之间所有奇数
numbers = [] for i in range(1,101): if (i % 2) == 1: numbers.append(i) print(
numbers)
输出1~100之间所有偶数
numbers = [] for i in range(1,101): if (i % 2) == 0: numbers.append(i) print(
numbers)
输出1~100之间所有奇数的和
numberSum = 0 for i in range(1,101): if (i % 2) == 1: numberSum += i print(
numberSum)
输出1~100之间所有偶数的和
numberSum = 0 for i in range(1,101): if (i % 2) == 0: numberSum += i print(
numberSum)
输出1~100之间所有质数
def prime(maxNumber): numbers = [] min = 2 while min <= maxNumber: is_prime =
True for i in range(2,min): if (min % i) == 0: is_prime = False break if
is_prime== True: numbers.append(min) min += 1 print('{0} 以下的质数有：'.format(
maxNumber)) print(numbers) print() #调用 prime(100)
输出1~100之间所有质数的和
# coding : utf-8 def prime(maxNumber): numbers = [] min = 2 numberSum = 0 while
min <= maxNumber: is_prime = True for i in range(2,min): if (min % i) == 0:
is_prime= False break if is_prime == True: numbers.append(min) min += 1 for i in
numbers: numberSum += i print('%s以内的质数和是：%s' % (maxNumber,numberSum)) prime(100
)
输出1~100所有合数
maxNumber = 100 numbers = [] min = 2 numberSum = 0 for i in range(1,101):
numbers.append(i) while min <= maxNumber: is_prime = True for i in range(2,min):
if (min % i) == 0: is_prime = False break if is_prime == True: numbers.remove(
min) min += 1 print(numbers)
输出1~100所有合数的和
maxNumber = 100 numbers = [] min = 2 numberSum = 0 for i in range(1,101):
numbers.append(i) while min <= maxNumber: is_prime = True for i in range(2,min):
if (min % i) == 0: is_prime = False break if is_prime == True: numbers.remove(
min) min += 1 for i in numbers: numberSum += i print('%s以内的合数和是：%s' % (maxNumber
,numberSum))
输出1~100所有数字
for i in range(1,101): print(i,end = ' ')
输出圆周率
from math import pi print('圆周率：',pi)
输出自然常量
from math import e print('自然常量：',e)
