pandas写入csv文件

import pandas as pd
a = ['one','two','three']
b = [1,2,3]
english_column = pd.Series(a, name='english')
number_column = pd.Series(b, name='number')
predictions = pd.concat([english_column, number_column], axis=1)
#another way to handle
save = pd.DataFrame({'english':a,'number':b})
save.to_csv('b.txt',index=False,sep='')
