>>> b = 'first \\n second \n third \\n forth \n fifth \\n'
>>> print(b)
first \n second
third \n forth
fifth \n
b 到想要的結果，
print( result )
first \n second third \n forth fifth \n
result = 'first \n second third \n Fourth Fifth \n'
怎么做？
uj5u.com熱心網友回復：
\n是轉義字符，表示換行符，while\\n是反斜杠和字母 n，洗掉時不受影響\n：
>>> b = 'first \\n second \n third \\n forth \n fifth \\n'
>>> b.replace('\n', '')
'first \\n second third \\n forth fifth \\n'
這個例子可能會讓你意識到它們之間的區別：
>>> len('\n')
1
>>> list('\n')
['\n']
>>> len('\\n')
2
>>> list('\\n')
['\\', 'n']
