一.python镜像布置
1.树形结构
2.dockerfile的编写
FROM python:3
MAINTAINER zyj<[email protected]>
WORKDIR /app
COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt -i https://pypi.douban.com/simple #修改源并安装依赖
ENTRYPOINT ["python"]
CMD ["helloworld.py"] #默认打开文件
3.requirements编写
PyMySQL
opencv-python
二、helloworld
vim helloworld.py
print("hello world")
三、日历编写
vim date.py
import calendar
# 输入指定年月
yy = int(input("输入年份: "))
mm = int(input("输入月份: "))
# 显示日历
print(calendar.month(yy,mm))
四、mysql操作
五、open-cv操作
#做一个图片翻转功能
import cv2
img=cv2.imread('test.jpg',flags=1)
rows,cols=img.shape[:2]
M=cv2.getRotationMatrix2D((cols/2,rows/2),90,1)
dst=cv2.warpAffine(img,M,(cols,rows))
cv2.imwrite("test-rotated.jpg", dst, [int(cv2.IMWRITE_JPEG_QUALITY), 100])
print('rotated and saved.')
