[英]how to convert folder of pickle files into single csv file
I have a directory containing about 1700 pickle file, that every file is all Twitter post of the user, I want to convert it into a folder of CSV files, that every CSV file name is the name of the pickle file and each row contains one tweet of user... after that, I want just the top 20 CSV with more samples than others... how can I do that?我有一个包含大约 1700 个 pickle 文件的目录,每个文件都是用户的 Twitter 帖子,我想将其转换为 CSV 文件的文件夹,每个 CSV 文件名都是 pickle 文件的名称,每行包含一个用户的推文……在那之后,我只想要前 20 个 CSV 的样本比其他人多……我该怎么做?
# khabarlist = open_file_linebyline(pkl_path)
def open_dir_in_dict(input_path):
files = os.scandir(input_path)
my_dict = {}
for file in files:
# if len(file.name.split()) > 1:
# continue
# if file.split('.')[-1] != "pkl":
with open(file, 'r', encoding='utf8') as f:
items = [i.strip() for i in f.read().split(",")]
my_dict[file.replace(".pkl", "")] = items
df = pd.DataFrame(my_dict)
df.to_excel(file.replace(".pkl", "") + "xlsx")
open_dir_in_dict("Raw/")
I Wrote the sample code for it and it did not work...我为它编写了示例代码,但它不起作用......
def open_dir_in_dict(input_path):
files = os.scandir(input_path)
my_dict = {}
for file in files:
if len(file.name.split()) > 1:
continue
if file.split('.')[-1] != "pkl":
with open(file, 'r', encoding='utf-8', errors='replace') as f:
print(f.readlines())
items = [i.strip() for i in f.read().split(",")] # encode('utf-8').strip()
my_dict[file.replace(".pkl", "")] = items
df = pd.DataFrame(my_dict)
df.to_excel(file.replace(".pkl", "") + "xlsx")
# open_dir_in_dict("Raw/")
and a better answer...和一个更好的答案......
import os
import pandas as pd
import regex as re
data_path = "/content/drive/My Drive/twint/Data/pkl/Data/"
for path in os.listdir(data_path):
my_tweets = []
df = pd.read_pickle(data_path + path)
for tweet in df.tweet:
url = re.findall(r"http\S+", tweet)
if url == []:
my_tweets.append(tweet)
new_df = pd.DataFrame({"tweets": my_tweets, "author": path.replace(".pkl", "")}) # path[:-4]
new_df.to_csv("/content/drive/My Drive/twint/final.csv", index=False, mode="a", )
