利用python将某列修改成另一列

import pandas
import os
f = open(r"C:\\Users\\zkk_f\\Desktop\\PLINK数据申请.csv","r",encoding="utf-8")
m = f.readlines()
huyan = {}
for line in m:
    line_new = line.strip("\n").split(",")
    huyan[line_new[1]] = line_new[0]
for key in huyan:
    print(key)
f.close()
f = open(r"C:\\Users\\zkk_f\\Desktop\\1635148881113_6302.vcf",encoding="utf-8")
f1 = open("xiugaiID.vcf","w",encoding= "utf-8")
mm = f.readline()
ko = mm.strip("\n").split("\t")
for huodu in  range(len(ko)):
    if "CEL" in ko[huodu]:
        yang = ko[huodu][4:17].replace("_","-")
        f1.write(huyan[yang]+ "\t")
    else:
        f1.write(ko[huodu] + "\t")
f1.write("\n")
mm = f.readlines()
for line in mm:
    line_new = line.strip("\n").split("\t")
    for ji in range(len(line_new)):
        f1.write(line_new[ji] + "\t")
    f1.write("\n")
f1.close()
