python之再学习----简单的文件

# filename:python3.1.py
# author:super
# date:2018-03-01


# with open(r'd:\test\test.txt') as file_object:
#     content = file_object.read()
#     print(content.rstrip())
#
# filename = r'd:\test\test.txt'
# with open(filename) as file:
#     for i in file:
#         print(i.rstrip())

# 用open方法就不用close()了 ， open里面会自带的
# 用open的时候那会又不想用这个文件， 可以用file.readlines() 存储起来
# 再用for来把readlines()里面的内容读出来
filename = r'd:\test\test.txt'
with open(filename) as files:
    lines = files.readlines()
pi_string = ''
# 在读取文件内容的时候，读出来的内容均为字符串， 如果要作为int来使用， 则要int()来转换
for line in lines:
    pi_string += line.strip()
    print(line.rstrip())
print(pi_string)
