如何将特殊字符更改为通常的字母？这是我的数据帧:
In [56]: cities
Out[56]:
Table Code Country Year City Value
240 Åland Islands 2014.0 MARIEHAMN 11437.0 1
240 Åland Islands 2010.0 MARIEHAMN 5829.5 1
240 Albania 2011.0 Durrës 113249.0
240 Albania 2011.0 TIRANA 418495.0
240 Albania 2011.0 Durrës 56511.0
我希望它看起来像这样:
In [56]: cities
Out[56]:
Table Code Country Year City Value
240 Aland Islands 2014.0 MARIEHAMN 11437.0 1
240 Aland Islands 2010.0 MARIEHAMN 5829.5 1
240 Albania 2011.0 Durres 113249.0
