我想将pandas.DataFrame对象保存到.csv文件中(使用DataFrame.to_csv())。为简单起见,情况就是这样;我的项目'Algos'包含文件夹'Plip',文件名为'plop.txt'。
1,2
3,4
5,6
我的脚本在这里:
import numpy as np
import pandas as pa
# opening the file
dossier = "Plip"
fichier = "plop.txt"
fichier = open(dossier + "/" + fichier)
data = fichier.readlines()
# creating the data frame
Pair = []
Impair = []
for m in data:
impair = int(m[0:1])
pair = int(m[2:3])
Impair.append(impair)
Pair.append(pair)
M = np.array([Impair, Pair]).transpose()
Table = pa.DataFrame(M, columns = ["Impair", "Pair"])
#creating the .csv file
Table.to_csv(dossier + fichier + ".csv")
表已正确创建,但脚本返回:
runfile('C:/Users/******/Documents/PYTHON/Algos/truc.py', wdir='C:/Users/******/Documents/PYTHON/Algos')
Traceback (most recent call last):

Table.to_csv(dossier + fichier + ".csv")
TypeError: Can't convert '_io.TextIOWrapper' object to str implicitly
我对Python很陌生,所以你能在答案上尽可能准确吗?
提前谢谢
答案 0 :(得分:0)
好像你将fichier
重新分配给L7上的文件对象,改为使用新变量!
