1、conda 源

  1. # win /user/.condarc
  2. # linux /root/.condarc
  3. show_channel_urls: true
  4. channels:
  5.   - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  6.   - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  7.   - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
  8.   - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge
  9.   - defaults

2、 时间转换

  1. # 字符串 转 datetime.datetime
  2. print(datetime.datetime.strptime("2022-06-07 12:00:00", "%Y-%m-%d %H:%M:%S"))
  4. # 字符串 转 timestamp
  5. print(datetime.datetime.strptime("2022-06-07 12:00:00", "%Y-%m-%d %H:%M:%S").timestamp())
  7. # datetime.datetime 转 字符串
  8. dtime = datetime.datetime.now()
  9. print(dtime.strftime("%Y-%m-%d %H:%M:%S"))
  11. # datetime.datetime 转 timestamp
  12. dtime = datetime.datetime.now()
  13. print(dtime.timestamp())
  15. # timestamp 转 datetime.datetime
  16. dtime = datetime.datetime.fromtimestamp(timestamps)
  17. print(dtime)
  19. # timestamp 转 字符串
  20. dtime = datetime.datetime.fromtimestamp(timestamps)
  21. print(dtime.strftime("%Y-%m-%d %H:%M:%S"))

3、Matplotlib

  1. # 支持中文
  2. plt.rcParams['font.sans-serif'] = ['SimHei']  # 用来正常显示中文标签
  3. plt.rcParams['axes.unicode_minus'] = False  # 用来正常显示负号
