我正在尝试运行以下Python代码以进行练习。
#!/bin/python3
import os
import sys
#
# Complete the maximumDraws function below.
#
def maximumDraws(n):
return n+1
if __name__ == '__main__':
fptr = open(os.environ['OUTPUT_PATH'], 'w')
t = int(input())
for t_itr in range(t):
n = int(input())
result = maximumDraws(n)
fptr.write(str(result) + '\n')
fptr.close()
但是我收到了这个错误信息
Traceback (most recent call last):
File "maximumdraws.py", line 13, in <module>
fptr = open(os.environ['OUTPUT_PATH'], 'w')
File "/home/inindekikral/anaconda3/lib/python3.6/os.py", line 669, in __getitem__
raise KeyError(key) from None
KeyError: 'OUTPUT_PATH'
我的操作系统是Linux Mint 19 Cinnamon。我该怎么做?
export OUTPUT_PATH='myfile'
