• 1 自己編寫一個(gè)乘法表，提示使用人輸入一個(gè)數(shù)字，并輸出乘法表。

如下

print "Which multiplication table  would you like?"
a =int(raw_input())
print "Here's your table:"
for i in range(1,11):
    print a ,'*',i,'=',a*i

run

Which multiplication table  would you like?
5
Here's your table:
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50```
######總結(jié)：
raw_input()函數(shù)輸出 str ,需要用int()轉(zhuǎn)換。

- 2 試著用while循環(huán) 完成上題

print "Which multiplication table would you like?"
a =int(raw_input())
print "Here's your table:"
i=1
while i<11:
print a ,'',i,'=',ai
i = i+1

*Run*

Which multiplication table would you like?
5
Here's your table:
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50```
總結(jié)：
這題難道我了，還好我想起了以前做過(guò)類似的循環(huán)練習(xí)，想到了自增 i = i+1 .
