我无法在pycharm和spyder上运行streamlit。我正在 window 上运行最新的 python 版本。当我尝试代码时，它说语法无效

#此代码用于在浏览器中打开streamlit

导入流线型 将streamlit导入为st 将 pandas 导入为 pd 从 FPL 导入 Predict_team、get_overview_data、extract_player_roster、
extract_teams_data、extract_player_types 将 matplotlib.pyplot 导入为 plt 将 numpy 导入为 np pd.options.display.float_format = "{:,.2f}".format

您的代码运行得非常好（我在下面附有的本地屏幕截图中运行）。

您没有提到如何运行代码，所以我假设您是通过spyder或pycham上的运行按钮运行的。所以，基本上这些按钮运行命令“python filename”。虽然在运行之前需要编译 stramlit 应用程序，所以请转到终端并运行命令 

streamlit run ***filename.py***

所以基本上代码需要使用streamlit命令而不是python运行。希望这会起作用。

运行此命令：streamlit run app.py

请按照以下步骤操作：

  1. 打开命令提示符
  2. cd（将目录更改为您的项目文件夹）
  3. 然后输入 
    streamlit run app.py
    （用你的 python 文件名更改 app.py）

使用命令提示符并转到存储 Streamlit 文件的项目目录。 比“streamlit run ”

之后将打开一个 url 页面，您可以在其中查看您的应用程序。
