如何使用 pandas 去除单个序列之间的新行。提前致谢!!

最佳答案

几乎根据定义，换行符是 CSV 文件的重要组成部分，因此无法让 Pandas 的 read_csv 忽略它们。最好是手动删除换行符，如下所示:

import pandas as pd
import re

with open ("seq.txt", "r") as myfile:
    data=myfile.readlines()

data = re.sub('\n', '', ''.join(data))
data = data.split(',')
df = pd.DataFrame([data], names=["id", "seq"])
