Question

有人可以帮帮我吗？我一直收到这个错误：

AttributeError：＆＃39; builtin_function_or_method＆＃39;对象没有属性＆＃39; count＆＃39;

这是我的代码：

fin=open("ah_d_01_CGATGT_L003_R1_001.fastq","r")
fout=open("ah_d_01_CGATGT_L003_R1_001.filt.fastq","w")
maxN=4
contatutte=containcl=0
seq=""
for line in fin:
    seq=fin.readline
    ctrl=fin.readline
    qual=fin.readline
    countN=seq.count("N", start=0, end=len(seq))
    if maxN>countN:
        fout.write(line)  #eventualmente aggiungi +"\n"
        fout.write(seq)
        fout.write(ctrl)
        fout.write(qual)
        containcl+=1
fin.close
fout.close
print contatutte,containcl

由于

Answer 1

您必须正确调用您的功能。在Python中，您不能省略()。

...
for line in fin:
    seq=fin.readline()
    ctrl=fin.readline()
    qual=fin.readline()
    ...

Answer 2

您需要对代码进行两处更改：

seq += fin.read()
countN = seq.count("N", 0, len(seq))

下面的代码没有任何错误，但您必须根据您的算法进行一些更改

fin=open("README.txt","r")
fout=open("submittest.txt","w")
maxN=4
contatutte=containcl=0
seq=""
seq += fin.read()
ctrl=fin.read()
qual=fin.read()
countN = seq.count("N", 0, len(seq))
if maxN>countN:
    #fout.write(line)  #eventualmente aggiungi +"\n"
    fout.write(seq)
    fout.write(ctrl)
    fout.write(qual)
    containcl+=1

fin.close
fout.close
print contatutte,containcl

或

fout=open("submittest.txt","w")
maxN=1000
contatutte=containcl=0
seq=""

with open('README.txt') as f:
    for line in f:
        seq += line
        ctrl = line
        qual = line
        countN = seq.count("N", 0, len(seq))
        if maxN>countN:
            #fout.write(line)  #eventualmente aggiungi +"\n"
            fout.write(seq)
            fout.write(ctrl)
            fout.write(qual)
            containcl+=1

        if 'str' in line:
            break

fout.close
print contatutte,containcl
