Python 从列表对象创建DataFramr

我得到一个错误：

dobj = {'reflectivity':pd.Series(np.array(gate_reflectivity)),#,index =list(range(len(gate_reflectivity)))),
        'RainRate':pd.Series(np.array(gate_RainRate)), #,index =list(range(len(mmlits)))),
        'Rainmm':pd.Series(np.array(Rainmm)) #,index =list(range(len(RainRate))))
        }
d = pd.DataFrame(dobj,columns =['reflectivity','RainRate','Rainmm'])
new_file = filenamex[:-2]+'txt'
open(new_file,'w')

np.savetxt(new_file,d,fmt='%10.5f',delimiter = ",",header =['reflectivity','RainRate','Rainmm'])

请帮助我

您可以使用参数

float\u格式

：

header = header.replace('\n', '\n' + comments)

AttributeError: 'list' object has no attribute 'replace'

---

请格式化您的代码。我正在从.Nc文件中提取一些变量并将它们写入新文件，并给出标题以了解哪个参数出现在哪个列中。超级，您可以添加

.Nc

文件（3,4行）的示例吗？

import pandas as pd

gate_reflectivity = [0,10.458682222]
gate_RainRate = [2,3.458771111]
Rainmm = [5,32.78542333333]


#if length of list is equal, omit index    
dobj = {'reflectivity':pd.Series(gate_reflectivity),
        'RainRate':pd.Series(gate_RainRate), 
        'Rainmm':pd.Series(Rainmm) 
        }
d = pd.DataFrame(dobj,columns =['reflectivity','RainRate','Rainmm'])
print (d)
   reflectivity  RainRate     Rainmm
0      0.000000  2.000000   5.000000

#writing
filenamex = 'aaaaa.Nc'
new_file = filenamex[:-2] + 'txt' 
d.to_csv(new_file, float_format='%10.5f', index=False)
