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

#

# 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)
