python的一个print问题

Question

python代码为：
with open ('test.txt') as test:
print(test)

test的内容为
1:test1
2:test2
3:test3

为什么结果显示为
<_io.TextIOWrapper name='test.txt' mode='r' encoding='cp936'>

Answer 1

with open('test.txt', 'r') as test:
    print(test.read())

Answer 2

你得调用read方法才能读出来内容呢把。这样只是读了个文件对象把？

Answer 3

with open ('test.txt') as test:
    for i in test.readlines():
        print(i)

Answer 4

for line in open(file_path):
    print(line.strip())
