Python字符串文字和转义序列

Question

I have a string

'"No, thanks, Mom," I said, "I don't know how long it will take."'

I assign it to a variable foobar

>>> foobar = """'"No, thanks, Mom," I said, "I don't know how long it will take."'"""

But when I print I get

>>> foobar
'\'"No, thanks, Mom," I said, "I don\'t know how long it will take."\''
>>>

How can I exactly print the same value of the string as I have assigned it?

Answer 1

To print a string, use ... print :

>>> foobar = """'"No, thanks, Mom," I said, "I don't know how long it will take."'"""
>>> print(foobar)
'"No, thanks, Mom," I said, "I don't know how long it will take."'

If you just enter foobar , Python prints the representation of foobar. The representation is designed to be valid Python code and/or useful for debugging, and is not meant to be outputted to users.

Answer 2

>>> print foobar

foobar , by itself, calls repr on the string, which prints the string with escapes. print foobar calls str on the string instead.

Answer 3

It is printing the same value. It is only showing you the single quote escaped to differentiate it from the single quote used by the cmd line to display of the string.
