方法一:

  1. def str_num(x):    #自定义一个函数,字符串列表,转成数字列表
  2.     aax=[]
  3.     for i in range(len(x)):
  4.         #print(b[i])
  5.         aax.append(eval(x[i]))
  6.     return aax
  8. aaa='15.34万31.87万23.42万26.18万57.04万14.10万47.59万47.11万17.57万14.27万35.78万14.47万72.96万46.14万28.30万76.00万28.68万134.74万58.27万14.66万15.67万24.36万16.87万20.22万14.18万198.39万22.46万15.37万26.05万24.25万23.84万'
  10. b=aaa[:-1].split('万')
  12. str_num(b)
