python文件读取

[2006班黄星瑶]

# 方式一
fin = open('poetry_num.txt', 'r', encoding='utf-8')
# open函数返回可迭代的文件对象
print(fin.read())
# 读全部内容到内存
fin.close()
# 记得关闭文件

# 方式二
lst = []
with open('poetry_num.txt', encoding='utf-8') as fin:
    str = fin.read()
    for x in str.split('\n'):
        lst.append(x)
print(lst)

# 方式三
lst = [line.strip() for line in open('poetry_num.txt', encoding='utf-8')]
print(lst)
