import os
def print_pos(dict1):
    keys=dict1.keys()
    keys=sorted(keys)
    for each in keys:
        print('关键字出现在%s行，%s个位置'% (each,str(dict1[each])))
        
def line_pos(each_line,key):
    pos=[]
    begin=each_line.find(key)
    while begin != -1:
        pos.append(begin+1)
        begin=each_line.find(key,begin+1)
    return pos
        
def file_line(each_file1,key):
    f=open(each_file1)
    count=0
    dict1=dict()
    for each_line in f:
        count+=1
        if key in each_line:
            pos=line_pos(each_line,key)
            dict1[count]=pos
    f.close()
    return dict1

def search_file(start_dir,key):
    os.chdir(start_dir)
    list_file=[]
    all_files=os.walk(os.curdir)
   
    for each_file in all_files:
        for i in each_file[2]:
            if '.txt' in i:
                temp1=os.path.join(each_file[0],i)
                list_file.append(temp1)
               
    for each_file1 in list_file:
        a=file_line(each_file1,key)
        if a:
            print('===============================================================')
            print('在文件%s中，找到关键词%s'% (each_file1,key))
            print_pos(dict1)         #是这里出错了吗？
        
start_dir=input('请输入要查找的目录：')
key=input('请输入要查找的关键词：')
search_file(start_dir,key)

为什么返回
Traceback (most recent call last):
  File "C:/Users/杜一鸣/Desktop/temp.py", line 49, in <module>
    search_file(start_dir,key)
  File "C:/Users/杜一鸣/Desktop/temp.py", line 44, in search_file
    print(dict1)
NameError: global name 'dict1' is not defined
请大神们帮看看，哪里错了，我分明定义过dict1了，谢谢！

我知道哪里错了，哈哈，柳暗花明

a换成dict1就行了
