用python修改.txt文件中的一行

Question

所以我试图修改文本文件中符合条件的多行。该行将以“ Section”开头，然后我将对该行进行一些修改，然后将旧行替换为新行。目前，我的代码看起来像这样，但是出现以下错误“ AttributeError：'str'对象没有属性'write'”]

for f in glob.glob('*.svp'):
    print(f)
    with open(f,'r+') as ins:
        fileArray = []
        for line in ins:
            fileArray.append(line)
            if "Section" in line:
                lat = line[26:35]
                lineToKeep = line[:33] #Portion of line without lat.## lon, what will be amended
                latAmended = round(float(lat[7:])*0.6)
                latAmended = str(latAmended).zfill(2)
                lon = line[36:46]
                lonToKeep = lon[:-2]
                lonAmended = round(float(lon[8:])*0.6)
                lonAmended = str(lonAmended).zfill(2)
                goodStuff = lineToKeep + latAmended + ' '+ lonToKeep + lonAmended
                line = goodStuff
            f.write(line)

Answer 1

注意，您正在使用文件路径'f'（一个'str'对象）而不是文件对象'ins'本身。更改最后一行的变量应该可以解决问题：

            ins.write(line)
