将字符串日期拆分为多个日期列表
将字符串日期拆分为多个日期列表
提问于 2020-01-20 17:25:36
我有下面的列表，我正在尝试将元素拆分成多个“日期”，我想写一个函数来做这件事，我不确定它正则表达式是go还是datetime
x=["2- 7 MAY, 2020, 10-12 JUN, 2014","7 February, 2020, 6 February, 2020, 26 October, 2018","16 JUN, 2020, 24 JUL, 2020, 28 FEB, 2020, 15 SEPT, 2020, 8-11 MAY, 2023, 22 OCT, 2020","14 JUN, 2020"]
for i in x:
temp=my_func(i)
if len(temp)==1:
date1=temp[0]
date2=""
elif len(temp)>=2:
date1=temp[0]
date2=temp[1]
else:
continue
#rest of my code以下是my_func的预期输出
#my_func(x[0])=["2- 7 MAY, 2020", "10-12 JUN, 2014"]
#my_func([x[1]])=["7 February, 2020", "6 February, 2020", "26 October, 2018"]
#my_func(x[-1])=["14 JUN, 2020"]回答 4

根据你的例子，
import re
for i in x:
temp =re.findall('\d.*?\d{4}',i)
#output
['2- 7 MAY, 2020', '10-12 JUN, 2014']
['7 February, 2020', '6 February, 2020', '26 October, 2018']
['16 JUN, 2020', '24 JUL, 2020', '28 FEB, 2020', '15 SEPT, 2020', '8-11 MAY, 2023', '22 OCT, 2020']
['14 JUN, 2020']Stack Overflow用户

使用','拆分字符串。总是有偶数个零件。两个相邻的部分组成一个日期。因此，只需将两个部分连接起来就可以形成一个日期字符串。
re很好，但下面的代码也应该是这样的：
>>> x = ["2- 7 MAY, 2020, 10-12 JUN, 2014","7 February, 2020, 6 February, 2020, 26 October, 2018","16 JUN, 2020, 24 JUL, 2020, 28 FEB, 2020, 15 SEPT, 2020, 8-11 MAY, 2023, 22 OCT, 2020","14 JUN, 2020"]
>>> result = []
>>> for s in x:
parts = s.split(',')
result.append([','.join(parts[i:i+2]).strip() for i in range(0,len(parts),2)])
>>> result
[['2- 7 MAY, 2020', '10-12 JUN, 2014'],
['7 February, 2020', '6 February, 2020', '26 October, 2018'],
['16 JUN, 2020', '24 JUL, 2020', '28 FEB, 2020', '15 SEPT, 2020', '8-11 MAY, 2023', '22 OCT, 2020'],
['14 JUN, 2020']
]您的my_func将非常简单：
>>> def my_func(s):
parts = s.split(',')
return [','.join(parts[i:i+2]).strip() for i in range(0,len(parts),2)]Stack Overflow用户

虽然使用了global Varibale，但输出结果与您希望的一样。程序取决于您格式化日期的方式。但是对于这种格式，它工作得很好。
dates=["2- 7 MAY, 2020, 10-12 JUN, 2014","7 February, 2020, 6 February, 2020, 26 October, 2018","16 JUN, 2020, 24 JUL, 2020, 28 FEB, 2020, 15 SEPT, 2020, 8-11 MAY, 2023, 22 OCT, 2020","14 JUN, 2020"]
def splitdates(date):
if type(date) is int:
tosplit = str(dates[date])
else:
tosplit = date
month = ["J" , "j" , "f" , "F" , "m" , "M" , "A" , "a" , "s" , "S" ,"n" , "N" , "o" , "O" , "D" , "d"]
for item, character in enumerate(tosplit):
if character in month:
for item2, character in enumerate(tosplit[item+1:]):
if character.startswith(","):
for item3, character in enumerate(tosplit[item+item2+2:]):
if character.startswith(","):
global newdate
newdate.append(tosplit[:item + item2 + item3 + 3])
nextPart = tosplit[item + item2 + item3 + 3:]
if nextPart.endswith(";"):
newPart = nextPart
splitdates(newPart)
else:
newdate.append(tosplit[item+item2+item3+3:])
return newdate
newdate.append(tosplit[:item+item2+item3])
return newdate
for x in range(len(dates)):
newdate = []
print("Date: ",splitdates(x))输出为：
Date: ['2- 7 MAY, 2020,', ' 10-12 JUN, 2014']
Date: ['7 February, 2020,', ' 6 February, 2020, 26 October, 2018']
Date: ['16 JUN, 2020,', ' 24 JUL, 2020, 28 FEB, 2020, 15 SEPT, 2020, 8-11 MAY, 2023, 22 OCT, 2020']
Date: ['14 JUN, 2']页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
