python 去掉.csv文件的重复行，去掉.txt重复行保存为.csv

数据集通常需要去掉文件中的重复行，以下是操作代码：

####将2个.csv拼接，并保存.csv文件

df1 = pd.read_csv(r'/Ce/NO.1/', header=None)#读取第一个文件

df2 = pd.read_csv(r'/Ce/NO.1/', header=None)#读取第二个文件

file1= [df1, df2]

outfile1 = (file1)#竖着拼接
outfile1.to_csv("/data/proteinall"+".csv", index=0, header=None, sep=',')

#####去掉重复行

inFile = open('/data/','r') #

outFile = open('/data/','w')  #最后保存的.csv文件

listLines = []

for line in inFile:

    if line in listLines:
        continue

    else:
        (line)
        (line)

()

()

以下是读取.txt，去掉重复行，保存为.csv

####加载.txt，去掉重复序列，保存为.csv
import numpy as np
import pandas as pd
import copy

def read_traingingData(file_name):
    # read sample from a file
    seq = []
    with open(file_name, 'r') as fp:
        i = 0
        for line in fp:
            (('\n')[0])
            i = i+1       
    return   seq  

file_1 = '/Ce/Ce.AC_N1.txt'

protein_A = read_traingingData(file_1)

df_protein=(protein_A)

seq_protein = df_protein.drop_duplicates()
seq_protein.to_csv('/home/aita/4444/LX/Ziqi/',index=0,header= None,encoding='gbk')
