File "D:\program\python\Python39\lib\site-packages\pymysql\connections.py", line 358, in __init__ self.connect()

根据提供的引用内容，可以看出这是在使用Python中的pymysql库连接数据库时出现的错误。具体来说，这个错误是由于端口号传递的不是数字类型导致的。解决这个问题的方法是将端口号转换为整数类型。可以使用int()函数将端口号转换为整数类型，例如：

port = '3306'
conn = pymysql.connect(host='localhost', port=int(port), user='root', password='123456', db='test')

另外，还可以检查一下端口号是否正确，以及是否有其他错误导致端口号无法正确传递。

这是一个 Python 中使用 PyMySQL 操作 MySQL 数据库时出现的错误。错误信息显示 SQL 语句存在语法错误，检查一下 SQL 语句的语法是否正确。根据错误信息，可能是 INSERT INTO 语句中字段名的格式不正确，或者是 VALUES 关键字缺失等问题导致的。建议将 SQL 语句拆分成多行，逐行检查语法是否正确。

File "d:\python 3.8\lib\site-packages\SCons\Script\Main.py", line 965, in _main

这个错误出现在SCons的Main.py文件的第965行。根据引用中的解决方法，你可以通过编辑TensorflowPlugin.py文件来解决这个错误。具体步骤为：在文件路径/home/wangsp/anaconda3/lib/python3.6/site-packages/nuitka/plugins/standard/TensorflowPlugin.py中找到第90行，将elements = module_name.split(".")修改为elements = module_name.getBasename()。

另外，你还可以尝试安装scons-4.0.0来解决这个问题。根据引用中的方法，你可以在终端输入以下命令来安装scons-4.0.0：
tar -xvf scons-4.0.0.tar.gz && cd SCons-4.0.0
sudo python3 setup.py install
注意，如果你的python版本不是3.8，那么应该相应地修改安装命令中的python版本号。

此外，根据引用中提供的信息，你还可以检查python模块的路径是否包含了/usr/local/lib/python3.8/dist-packages和/usr/lib/python3/dist-packages。

总结一下，要解决File "d:\python 3.8\lib\site-packages\SCons\Script\Main.py", line 965, in _main的错误，你可以尝试以下几个方法：
1. 编辑TensorflowPlugin.py文件，修改对应代码行。
2. 安装scons-4.0.0。
3. 检查python模块的路径是否正确。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
