使用下面的代码,我不断收到错误。我有一个非常相似的示例代码,但这个代码似乎不起作用。此外,我确实通过regex101.com运行我的正则表达式,所以它应该工作。
Uri uriAudio = Uri.fromFile(new File(audioFilePath).getAbsoluteFile());
final StorageReference filePath = ref.child("Education/image").child(uriImage.getLastPathSegment());
final StorageReference audioRef = ref.child("Education/audio").child(uriAudio.getLastPathSegment());
// on success upload audio
audioRef.putFile(uriAudio).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(final UploadTask.TaskSnapshot audioSnapshot) {
//upload image
filePath.putFile(uriImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(final UploadTask.TaskSnapshot imageSnapshot) {
mProgress.dismiss();
@SuppressWarnings("VisibleForTests") Uri audioUrl= audioSnapshot.getDownloadUrl();
@SuppressWarnings("VisibleForTests") Uri imageUrl= imageSnapshot.getDownloadUrl();
代码:
Traceback (most recent call last):
File "/Users/name/Assignment 3.py", line 8, in <module>
print(re.match(pattern, file1))
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/re.py", line 137, in match
return _compile(pattern, flags).match(string)
TypeError: expected string or buffer
答案 0 :(得分:1)
我猜你真正想要的是查看文件的内容:
with open("10000DirtyNames.csv", "r") as file1:
if (re.search(pattern, file1.read()):
print("Match")
else:
print("Does not match")
此外,re.search()
和re.match()
之间存在差异,后者仅在字符串的开头起作用(因此,隐式设置了锚点)。
最后,可以通过None
或仅使用is not None
if x:
