您能帮我得到每次出现两个字符之间的子字符串吗?
例如,在所有出现的情况下,获取给定示例序列中“Q”和“E”之间的所有子字符串:
ex: QUWESEADFQDFSAEDFS
并找到具有最小长度的子字符串。
最佳答案
import re
DATA = "QUWESEADFQDFSAEDFS"
# Get all the substrings between Q and E:
substrings = re.findall(r'Q([^E]+)E', DATA)
print "Substrings:", substrings
# Sort by length, then the first one is the shortest:
substrings.sort(key=lambda s: len(s))
print "Shortest substring:", substrings[0]
