無效synax關閉文件

def td(): 

    choice = input("which trainning event would you like to access?\nswimming\ncycling\nrunning\n") 
    if choice == "swimming": 
    Swimming_file= open("Swimming_file.txt", "w") 

totaldistance = input("what was the total distance you swam in meters?") 
totaltime = input("how long did you swim for in minutes?") 

total = (totaldistance, toataltime) 
Swimming_file.write(str(total) 
Swimming_file.close() 
td()

它一直說swim_file.close（）是一個synax錯誤，任何人都可以幫忙嗎？無效synax關閉文件
