'''
# 打开文件以编辑('w'riting)
f = open('poem.txt', 'w')
# 向文件中编写文本
f.write(poem)
# 关闭文件
f.close()
# 如果没有特别指定
# 将假定启用默认的阅读('r'ead)模式
f = open('poem.txt')
while True:
line = f.readline()
# 零长度指示 EOF , 用来判断文档结尾
if len(line) == 0:
break
# 每行('line')的末尾
# 都已经有了换行符
# 因为它是从一个文件中进行读取的
print(line, end=' ')
# 关闭文件
f.close()
运行结果
