Python基础

Posted 2020-10-27 wha000

Pycharm开发环境设置与熟悉。

 

练习基本输入输出：

print(\'你好,{}.\'.format(name))

uprint(sys.argv)

 

库的使用方法：

import ...

from ... import ...

 

条件语句：

    if (abs(pos()))<1:

        break

 

循环语句：

for i in range(5):

while True:

 

函数定义：

def mygoto(x,y):

def drawjx(r):

 

综合练习：画一面五星红旗，将代码与运行截图发布博客交作业。

from turtle import *

def mygoto(x,y):
    up()
    goto(x,y)
    down()

setup(600,400,0,0)
color(\'yellow\')
bgcolor(\'red\')
fillcolor(\'yellow\')

mygoto(-250,75)
begin_fill()
for i in range(5):
    forward(100)
    right(144)
end_fill()

mygoto(-100,150)
begin_fill()
for i in range(5):
    forward(50)
    right(144)
end_fill()

mygoto(-50,100)
begin_fill()
for i in range(5):
    forward(50)
    right(144)
end_fill()

mygoto(-50,50)
begin_fill()
for i in range(5):
    forward(50)
    right(144)
end_fill()

mygoto(-100,0)
begin_fill()
for i in range(5):
    forward(50)
    right(144)
end_fill()

done()
