目标是获取“%”之后“--”之前的文本。你知道吗
然而,有时文本会在'--'之前被剪掉,就像在一个随机的字母上一样。为什么不能正常工作?提前谢谢!PS使用Python3.5。你知道吗
if destiny=='fortune':
fortuneformat= fortune_print.split('%')[-1]
print (fortuneformat)
_1_fortuneformat= fortuneformat.split("--")[0]
fortunesay = str(_1_fortuneformat)
仅供参考:
fortune_print= get_random_fortune('quotes1.txt')
这是用来发财的函数。你知道吗
def get_random_fortune(fortune_file):
"""

``.dat`` file isn't present.byt

fortune_index_file = fortune_file + '.dat'

f.close()
return fortuneCookie
从提供输入的文本文件中输入财富的示例:

The NSA knows what you did last summer. But no one, in the NSA or outside it,
knows why they should.

-- NSA Facts by Shlomi Fish and Friends ( http://www.shlomifish.org/humour/bits/facts/NSA/ )
预期输出:The NSA knows what you did last summer. But no one, in the NSA or outside it, knows why they should.
实际输出:The NSA knows what yo
有人问我腌过的文件是怎么做的。一切都结束了pickle.dump公司在此函数中:
def make_fortune_data_file(fortune_file, quiet=False):
"""
Create or update the data file for a fortune cookie file.
:Parameters:
fortune_file : str
path to file containing fortune cookies
quiet : bool
If ``True``, don't display progress messages
"""
fortune_index_file = fortune_file + '.dat'
if not quiet:
pass
#print ('Updating "%s" from "%s"...' % (fortune_index_file, fortune_file))
data = []
shortest = sys.maxsize
longest = 0
for start, length, fortune in _read_fortunes(open(fortune_file, 'rU')):
data += [(start, length)]
shortest = min(shortest, length)
longest = max(longest, length)
fortuneIndex = open(fortune_index_file,'wb')
pickle.dump(data, fortuneIndex,protocol=4,fix_imports=True)
fortuneIndex.close()
为什么不直接用正则表达式来寻找财富呢?你知道吗
