Python处理文本换行符

源文件内容如下：

源文件每行后面都有回车，所以用下面输出时，中间会多了一行

>>> try:
    with open(r"C:\Users\Administrator\Desktop\20190506biji0.txt" ) as f :
        for line in f:
            print(line)
except FileNotFoundError:
    print("读取文件出错")

    
hello world

how are you？

I am fine

有两种方法处理：

1.print后面带 end=’’,表示不换行

>>> try:
    with open(r"C:\Users\Administrator\Desktop\20190506biji0.txt" ) as f :
        for line in f:
            print(line,end='')
except FileNotFoundError:
    print("读取文件出错")

    
hello world
how are you？
I am fine

2.用strip()函数去掉每一行的换行符

>>> try:
    with open(r"C:\Users\Administrator\Desktop\20190506biji0.txt" ) as f :
        for line in f:	
            line=line.strip('\n')
            print(line)
except FileNotFoundError:
    print("读取文件出错")

    
hello world
how are you？
I am fine

再者：

>>> x='''hello world
how are you？
I am fine'''
>>> x.strip('\n')
'hello world\nhow are you？\nI am fine'
>>> print(x,end='')
hello world
how are you？
I am fine
>>> print(x)
hello world
how are you？
I am fine
