出现这个错误是因为在Python中,变量名和赋值运算符之间不能有空格。正确的代码应该是:
```python
nullCount = data.select([count(when(col(c).isNull(), c)).alias(c) for c in data.columns]).show()
```
这里使用了`when`函数来判断每列是否为空,再使用`count`函数来计算每列中空值的数量。最后使用`alias`函数给每列命名,并使用`show`函数将结果打印出来。

File "<ipython-input-6-6a8f9a768616>", line 1 1.import tkinter as tk ^ SyntaxError: invalid synta
这个错误提示表明你在代码的第一行使用了错误的语法。在Python中,导入模块的正确语法是:
```
import 模块名
```
请检查你的代码,确认是否正确导入了 tkinter 模块,并且没有使用任何无效的语法。如果有更多的错误信息,请提供更多的上下文和代码。
File "<ipython-input-64-596064a8c0f8>", line 5 cal_num = x_series.value_counts() ^ IndentationError: unexpected indent
This error message indicates that there is an unexpected indentation in the code. The indentation should be consistent throughout the code, and any blocks of code that are intended to be executed together should be indented at the same level.
To fix this error, check the indentation of the line of code mentioned in the error message (line 5 in this case). Make sure that it is properly indented and there are no extra spaces or tabs that could be causing the issue. Also, check the indentation of the preceding lines of code to ensure that they are consistent with the rest of the code.
