这是一段比较文件的代码，求解为什么找出相同的文件的代码没有运行，即
else:
print ("hahaha")
file1 = os.path.join(dir1_root,file_path)
file2 = os.path.join(dir2_root,file_path)
if md5(file1) != md5(file2):
results[file_path] = "这是不同于目录2中的文件"
print ("这是不同于目录2中的文件")
else:
results[file_path] = "这是相同的文件"

好像根本就没有运行到这段代码

python中的字典赋值问题？？？
