二、python開(kāi)發(fā)軟件PyCharm的安裝

注冊(cè)碼的獲取：http://idea.lanyus.com

三、練習(xí)基本語(yǔ)法

1.1if判斷

代碼塊

age=input('是否成年')

age=int(age)

if number>=18:

print('成年')

else:

print('未成年')

2、計(jì)算 1 ~ 100之間的累加和

i = 1

sum_num = 0

while i <= 100:

# sum_num = sum_num + i

sum_num += i

i += 1

print(sum_num)

3、跳出循環(huán)break

i=1
sum = 0
while i <= 100:
sum += i
if sum > 1000:
breaki += 1
print(sum)

4、計(jì)算所有奇數(shù)的和

i = 1
sum = 0
while i <= 100:
% 取模  
//整除
if i % 2 == 0:
i += 1
continuesum += i
i += 1
print(sum)
