使用文件功能时出现错误信息

Question

这是怎么回事？我尝试在函数中读取我的txt文件。：

def vragen_ophalen():
    text_file = open("vragen.txt", "r")
    print(text_file.read())



def main():
    vragen_ophalen()

if __name__ == "__main__":
    main()  

错误消息：

Traceback (most recent call last):
  File "/Users/buni/Desktop/Leiden/iipr/Huiswerk python/sorteerhoed_concept.py", line 11, in <module>
    main()  
  File "/Users/buni/Desktop/Leiden/iipr/Huiswerk python/sorteerhoed_concept.py", line 8, in main
    vragen_ophalen()
  File "/Users/buni/Desktop/Leiden/iipr/Huiswerk python/sorteerhoed_concept.py", line 2, in vragen_ophalen
    text_file = open("vragen.txt", "r")
