rs41453844=CT rs36005134=AT rs41518851=AG rs2287980=GT rs28526632=AG rs41342447=AG rs41444944=AG (310, 0.206117)

rs41453844=CT rs36005134=AT rs41518851=AG rs2287980=GT rs28526632=AG rs41342447=AG (422, 0.280585)

有人能帮我用python代码去掉括号里的数字吗？我只想把rs#保存在一个新的.txt文件中。谢谢。你知道吗

Answer 1

怎么样

line = line.split("(")[0]

（第一个(字符前面的所有内容）

所以你的程序有点像

with open("rs.txt") as inf, open("new.txt", "w") as outf:
    for line in inf:
        line = line.split("(", 1)[0].rstrip() + "\n"
        outf.write(line)
