We would like to list the following strings using the regular expression re.findall to obtain up to two units: numeric values and ms and MB.I could get up to the number, but I couldn't get the credit.
In order to make the string look like the following list, I want to get both initials and endings at the same time, but the way to do it is
I don't know. It may be a rudimentary question, but I would appreciate it if you could let me know.
'Duration: 123.45 ms\tBuild Duration: 123 ms\tMemory Size: 123 MB\tMax Memory Used: 123 MB\tInit Duration: 1234.56 ms'
['123.45ms', '123ms', '123MB', '123MB', '1234.56ms']
After learning about regular expressions, I was able to get numbers first.
string='Duration: 123.45 ms\tBuild Duration: 123 ms\tMemory Size: 123 MB\tMax Memory Used: 123 MB\tInit Duration: 1234.56 ms'
stringlist=re.findall(r'\d+\.\d+|\d+',string)
Next, I know I'll use $ when I end it, so I coded it as follows, but I couldn't get anything as a list.
string='Duration: 123.45 ms\tBuild Duration: 123 ms\tMemory Size: 123 MB\tMax Memory Used: 123 MB\tInit Duration: 1234.56 ms'
stringlist=re.findall(r'\d+\.\d+ms$|\d+ms$',string)
import re
string = 'Duration: 123.45 ms\tBuild Duration: 123 ms\tMemory Size: 123 MB\tMax Memory Used: 123 MB\tInit Duration: 1234.56 ms'
US>stringlist=re.findall(r'(\d+(?\.\d+)?+?)(?=\t|$), string)
print(stringlist)
# ['123.45ms', '123ms', '123MB', '1234.56ms']
When using re.split()
stringlist=re.split(r':|\t', string)[1::2]
print(stringlist)
# ['123.45ms', '123ms', '123MB', '1234.56ms']
I don't mind anything, but I thought it would be better to use a Match object.( Contrary to what I want to do, I don't use findall)
import re
string = 'Duration: 123.45 ms\tBuild Duration: 123 ms\tMemory Size: 123 MB\tMax Memory Used: 123 MB\tInit Duration: 1234.56 ms'
stringlist = [m[0] for min re.finder('(\d+(?:\.\d*)?)(?:(ms|MB)))?',string)]
print(stringlist)
# ['123.45ms', '123ms', '123MB', '1234.56ms']
