如何阅读gzip：'GzipFile'对象没有属性'extrastart''

Question

我想阅读gzip并更新内容。

然而，我收到错误

  

'AttributeError：'GzipFile'对象没有属性'extrastart''。

import gzip                                                 

with gzip.open("PhoneWindowManager.java.gz", "w+") as file: 
    for line in file:                                       
        if "setHdmiPlugged" in line:                        
            call = "#setHdmiPlugged"                        
            if call in line:                                
                continue                                    
            else:                                           
                print line                                  
                break

extrastart仅在模式以'r'开头时设置，

with gzip.open("PhoneWindowManager.java.gz", "r") as file://change "w+" to "r+"
