Pandas: astype error string to float (could not convert string to float: '7,50')
提问by FilipB
I am trying to convert a dataframe field from string to float in Pandas.
我正在尝试将数据帧字段从字符串转换为 Pandas 中的浮点数。
This is the field:
这是字段:
In:
print(merged['platnosc_total'].head(100))
Out:
0 0,00
1 4,50
2 0,00
3 0,00
4 0,00
5 4,50
6 6,10
7 7,99
8 4,00
9 7,69
10 7,50
Note the 7,50, in the last row, which seems to cause the error:
请注意最后一行中的 7,50,这似乎导致了错误:
In:
merged['platnosc_total'].astype(float)
Out:
ValueError: could not convert string to float: '7,50'
Does this mean that the rest got converted, and only the row with 7,50 is the cause?
这是否意味着其余的都被转换了,只有 7,50 的行是原因?
How can I actually cast this field/column to float?
我如何才能真正将此字段/列转换为浮动?
