[已解决]仿照写的课后作业，还没咋运行，每次都显示最后一行有问题 invalid synatx

xh8293

是不是我哪里有问题，导致最后一步，无法调用函数，一调用就出错
import os

def pos_in_line (line,key):
    pos= []
    begin = line.find(key,0)
    if begin != -1:
        pos.append (begin+1)
        begin = line.find(key,begin+1)
    return pos
def pos_in_file (file , key):
    f = open (file)
    count = 0
    key_dict= dict()
    for each_line in file:
        count +=1
        key_dict[count] = pos_in_line (each_line ,key)
    f.close()
    return key_dict

def search_files(key,path):
    txt_files=[]
    dict1= dict()
    for root,dirs, files in os.walk(path):
        for name in files:
            if os.path.splitext[1]== '.txt':
                txt_name = os.path.jion(root,name)
                txt_files.append (text_name)
    for file in txt_files:
        dict1 = pos_in_file (file , key)
        num = dict1.key()
        num = sorted(num)
        for each in num:
            print ('在有%s处，关键字位于%s，第%s个位置' % (file, num, dict1[num])

print ('在有%s处，关键字位于%s，第%s个位置' % (file, num, dict1[num]))

少了个括号，补上就行了
