大家好我是python的新手,非常感谢你的帮助!
我有这样的多个字符串:
21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38
我正在试图找出如何基于一组单词(即"Mckenzie Meadows Golf Course"
)分割线条及其周围的引号和双引号。
然后我将字符串重新排列为这种格式:
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
重新排列我只会使用
for row in data:
outfile.write('{0} {1} {2} {3} {4}'.format(row[2], row[0], row[1], row[3], row[4]))
outfile.write('\n')
但是我只是不确定如何从单行引出单句。谢谢你的帮助!

你可以试试这个:
s = "21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38"
sList = s.split(' ')
words = []
nums = []
for l in sList:
if l.isalpha():
words.append(l)
elif l.isdigit():
nums.append(l)
wordString = "\"%s\"" % " ".join(words)
row = [wordString] + nums
此时,row
包含您想要的行。

这就是我这样做的方式:
import re
tgt='21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38'
nums=[m.group() for m in re.finditer(r'[\d\.]+',tgt)]
words=[m.group() for m in re.finditer(r'[a-zA-Z]+',tgt)]
print '"{}" {}'.format(' '.join(words),' '.join(nums))
打印:
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
或者,你可以测试Python认为是浮点数来找到它们:
nums=[]
words=[]
for e in tgt.split():
try:
nums.append(float(e))
except ValueError:
words.append(e)
print words,nums
最后,如果你有固定格式的4个浮点数和一个字符串(float,float,string,float,float),你可以这样做:
li=tgt.split()
nums=' '.join(li[0:2]+li[-2:])
words=' '.join(li[2:-2])
print words,nums
答案 2 :(得分:1)
使用正则表达式的代码:
import re
s = '21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38'
row = re.search('([0-9.]+)\s([0-9.]+)\s([\w ]+)\s([0-9.]+)\s([0-9.]+)', s)
if row:
print '"{0}" {1} {2} {3} {4}'.format(row.group(3), row.group(1), row.group(2), row.group(4), row.group(5))
将打印(带双引号):
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
答案 3 :(得分:0)
使用str
方法:
>>> s = '21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38'
>>> temp = s.split()
>>> temp
['21357.53', '84898.10', 'Mckenzie', 'Meadows', 'Golf', 'Course', '80912.48', '84102.38']
>>> row = [temp[0], temp[1], '"'+' '.join(temp[2:-2])+'"', temp[-2], temp[-1]]
>>> row
['21357.53', '84898.10', '"Mckenzie Meadows Golf Course"', '80912.48', '84102.38']
>>> print '{0} {1} {2} {3} {4}'.format(row[2], row[0], row[1], row[3], row[4])
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
答案 4 :(得分:0)
>>> words = "21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38".split()
>>> print '"%s" %s'%(" ".join(filter(lambda x: x.isalpha(), words)), " ".join(filter(lambda x: not x.isalpha(), words)))
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
更严格地说,不假设所有非alpha字都是浮点数(使用reduce
):
>>> words = "21357.53 84898.10 Mckenzie Meadows Golf Course 80912.48 84102.38".split()
>>> print '"%s" %s'%(" ".join(filter(lambda x: x.isalpha(), words)), " ".join(filter(lambda x: reduce(lambda y, z: z.isdigit() and z, x.split('.'), True), words)))
"Mckenzie Meadows Golf Course" 21357.53 84898.10 80912.48 84102.38
