python - 来自 json 响应的解码二进制内容的行数

Question

我在下面有一些代码计算解码后的 GitHub 二进制内容中的行数，然后根据文件的更改计数查找百分比更改。这包含在 if/else 语句的循环中的循环中。我现在所做的工作，但它输出拉取请求中每个单独文件的结果。如果返回文件集中的任何结果满足 if 语句中的条件(否则打印没有文件已更改)，我想只写一次 if/else，然后继续进行下一组评估。

     found = False
     for data in repo.pull_request(prs.number).files():
         if data.filename.endswith((".png",".jpeg",".gif")):
             pass
         else:
             for files_content in [repo.blob(data.sha)]:
                 binary_coded_content = io.BytesIO((base64.b64decode(files_content.content)))
                 tempfile = 'temp'
                 with open(tempfile,'wb') as f:
                     f.write(binary_coded_content.read())
                 num_lines = sum(1 for line in open(tempfile, encoding='utf8') if line.rstrip())
                 if data.changes_count/num_lines > 0.25:
                     found = True
                     break
     if found:
         print("A file has changed by more than 25%", '\n')
     else:
         print("No file has changed by more than 25%", '\n')

如果我理解正确的话，您想创建一个found 变量并像这样在循环外测试它

found = False # <----
for data in repo.pull_request(prs.number).files():
    if data.filename.endswith((".png",".jpeg",".gif")):
        pass
    else:

        for files_content in [repo.blob(data.sha)]:
             binary_coded_content = io.BytesIO((base64.b64decode(files_content.content)))
             tempfile = 'temp'
             with open(tempfile,'wb') as f:
                 f.write(binary_coded_content.read())
             num_lines = sum(1 for line in open(tempfile, encoding='utf8') if line.rstrip()) 
             if data.changes_count/num_lines > 0.25:
                found = True # <----
                break #<--- break inner loop
        if found:
            break #<--- break outer loop
    if found: # after the loop ended, we check if we found something...
        print("A file has changed by more than 25%")
    else:
        print("No file has changed by more than 25%")
