CSV文件分隔符转换
CSV文件系统默认分隔符是逗号(,),但是如果自定义过分隔符,再次保存就会变成分号(;),此时再用逗号去读数据时程序会报错。
例如设置csv格式如下:
Python方法
Traceback (most recent call last):
File "xxx\Python39\lib\site-packages\pandas\core\indexes\base.py", line 3652, in get_loc
return self._engine.get_loc(casted_key)
File "pandas\_libs\index.pyx", line 147, in pandas._libs.index.IndexEngine.get_loc
File "pandas\_libs\index.pyx", line 176, in pandas._libs.index.IndexEngine.get_loc
File "pandas\_libs\hashtable_class_helper.pxi", line 7080, in pandas._libs.hashtable.PyObjectHashTable.get_item
File "pandas\_libs\hashtable_class_helper.pxi", line 7088, in pandas._libs.hashtable.PyObjectHashTable.get_item
此时修改为默认系统分隔 或者改为Decimal用句号,Thousands用逗号,再次保存csv文件则不会有此问题
注意 保存时选择逗号分隔:
