我有一列,其中包括stay_in_current_city_years。 还有一些数据,例如4 +
我想要一些算法。首先是线性回归
from sklearn.linear_model import LinearRegression
r=LinearRegression()
r.fit(x_train,y_train)
y_pred=r.predict(x_test)
print(y_pred)
ValueError:无法将字符串转换为float:'4 +'
答案 0 :(得分:-2)
如果您要删除+,那么最容易理解的删除方法是:
str = '4+'
str = str.replace('+', '') # this will replace the '+' with ''
str = str.strip() # this will remove the leading and trailing spaces, just in case, good practice, but might not be required, voila you have just the number
