Python 获取奇数和偶数

获取奇数

#!/usr/bin/python3
# -*- coding:utf-8 -*-
for i in range(1,11):
    if (i % 2) == 0:
    continue
else:
    print(“{0} is odd”.format(i))
执行结果:
1 is odd
3 is odd
5 is odd
7 is odd
9 is odd

获取偶数

#!/usr/bin/python3
# -*- coding:utf-8 -*-
for i in range(1,11):
    if (i % 2) == 0:
    print(“{0} is even”.format(i))
执行结果:
2 is even
4 is even
6 is even
8 is even
10 is even

判断奇偶数

# Python 判断奇数(odd)偶数(even)
# 如果是偶数除于 2 余数为 0
# 如果余数为 1 则为奇数

#!/usr/bin/python3
# -*- coding:utf-8 -*-
num = int(input(“Please input number: “))
if (num % 2) == 0:
print(“{0} is even”.format(num))
else:
print(“{0} is odd”.format(num))

九九乘法表

#!/usr/bin/python3
# -*- coding:utf-8 -*-
#通过指定end参数的值 可以取消在末尾输出回车符 实现不换行
for i in range(1, 10):
for j in range(1, i+1):
print(‘{}x{}={}\t’.format(j, i, i*j), end=”) print()

输出结果:
1×1=1
1×2=2 2×2=4
1×3=3 2×3=6 3×3=9
1×4=4 2×4=8 3×4=12 4×4=16
1×5=5 2×5=10 3×5=15 4×5=20 5×5=25
1×6=6 2×6=12 3×6=18 4×6=24 5×6=30 6×6=36
1×7=7 2×7=14 3×7=21 4×7=28 5×7=35 6×7=42 7×7=49
1×8=8 2×8=16 3×8=24 4×8=32 5×8=40 6×8=48 7×8=56 8×8=64
1×9=9 2×9=18 3×9=27 4×9=36 5×9=45 6×9=54 7×9=63 8×9=72 9×9=81

十进制转二进制、八进制、十六进制

#!/usr/bin/python3
# -*- coding:utf-8 -*-
# 获取用户输入十进制数
dec = int(input(“Please input number:”))
print(“十进制数为:”, dec)
print(“转换为二进制为:”, bin(dec))
print(“转换为八进制为:”, oct(dec))
print(“转换为十六进制为:”, hex(dec)
