python九九乘法表和列印圖形程式

標籤：python   乘法表   

一、列印九九乘法表：

#coding:utf-8for i in range(1,10):    for j in range(1,i+1):        print("%dx%d=%d") %(j,i,j*i),    print ‘\n‘

結果:

650) this.width=650;" title="99.png" alt="wKiom1lLma-Trl7_AAASsxiCmSs619.png-wh_50" src="https://s1.51cto.com/wyfs02/M02/99/BB/wKiom1lLma-Trl7_AAASsxiCmSs619.png-wh_500x0-wm_3-wmp_4-s_2116397384.png" />

二、列印正方形

實體正方形 代碼：

#coding:utf-8rows=int(raw_input("輸入正方形邊長:"))for i in range(rows):    for j in range(rows):        print("*"),    print

650) this.width=650;" title="11.png" alt="wKiom1lLmjOB5V6CAAAD1-Cabjk846.png-wh_50" src="https://s5.51cto.com/wyfs02/M02/99/BB/wKiom1lLmjOB5V6CAAAD1-Cabjk846.png-wh_500x0-wm_3-wmp_4-s_1253390052.png" />

空心正方形 代碼：

#coding:utf-8rows=int(raw_input("輸入正方形邊長:"))for x in range(rows):    for y in range(rows):        if x !=0 and x != rows-1:            if y==0 or y == rows-1:                print(" * "),            else:                print("   "),        else:             print(" * "),    print("\n")

效果：

650) this.width=650;" title="22.png" alt="wKioL1lLmoWSH8xxAAAHnVE_ymM763.png-wh_50" src="https://s1.51cto.com/wyfs02/M00/99/BB/wKioL1lLmoWSH8xxAAAHnVE_ymM763.png-wh_500x0-wm_3-wmp_4-s_3653282803.png" />

三、列印聖誕樹

代碼：

#coding:utf-8rows=3for x in range(rows):    for i in range(1,13):        if i % 2 ==0:            continue        else:            print(str(i * ‘*‘).center(11))for y in range(10):    print(‘*‘.center(11))

效果：

650) this.width=650;" title="333.png" alt="wKioL1lLmuDwveUfAAAIH4QbHJ0392.png-wh_50" src="https://s2.51cto.com/wyfs02/M01/99/BB/wKioL1lLmuDwveUfAAAIH4QbHJ0392.png-wh_500x0-wm_3-wmp_4-s_275057874.png" />

四、列印淩形

代碼：

#coding:utf-8rows=10#while True:for i in range(1, rows):    if i % 2 == 0:        continue    else:        print(str(i * ‘*‘).center(rows))for i in range(rows):    if i % 2 == 0:        continue    else:        print(str((rows - i) * ‘*‘).center(rows))

效果：

650) this.width=650;" title="88.png" alt="wKiom1lLm-ahewALAAADRywHOoo780.png-wh_50" src="https://s4.51cto.com/wyfs02/M00/99/BB/wKiom1lLm-ahewALAAADRywHOoo780.png-wh_500x0-wm_3-wmp_4-s_3866568092.png" />
