我的数据范围是从-100到100的负浮点数，我想通过以下方式更改此数据：
from 0 to 1 - ss
from 1 to 2 - sm
from 2 to 3 - sa
> 3 s
from 0 to -1 - bs
from 1 to -2 - bm
from 2 to -3 - ba
< 3 b
怎么办
谢谢
请检查以下解决方案：
import pandas as pd
y = pd.DataFrame({"Data": [1.1, 1.3, 2.5, 3.9, -0.7, -1.3, -2.6, -9]})
def change_func(x):
if x <= -3:
return "b"
elif -3 < x <= -2:
return "ba"
elif -2 < x <= -1:
return "bm"
elif -1 < x <= 0:
return "bs"
elif 0 < x <= 1:
return "ss"
elif 1 < x <= 2:
return "sm"
elif 2 < x <= 3:
return "sa"
else:
return "s"
y["New_Column"] = y["Data"].apply(lambda x: change_func(x))
# if you do not want new line you can do the following:
# instead of y["New_Column"] = y["Data"].apply(lambda x: change_func(x) let's do:
# y["Data"] = y["Data"].apply(lambda x: change_func(x))
print(y)
希望对您有所帮助，让我知道问题是否解决，随时提出问题。
