我在文本文件中有以下数据。
[Test id_g001,**Test id_g002,Test id_g000, Value_is_0, Value_is_2, Value_is_1]
我只能对数据进行排序。如何并行排序数据,因此数据将按如下方式排序?测试ID和值都需要排序
Test ID ---------------Value
g000 ------------------- 0
g001 ------------------- 1
g002 ------------------- 2
代码是:
def readFile():
from queue import PriorityQueue
q = PriorityQueue()
#try block will execute if the text file is found
try:
fileName= open("textFile.txt",'r')
for line in fileName:
for string in line.strip().split(','):
q.put(string[-4:])
fileName.close() #close the file after reading
print("Displaying Sorted Data")
while not q.empty():
print(q.get())
#catch block will execute if no text file is found
except IOError:
print("Error: FileNotFoundException")
return
答案 0 :(得分:0)
我们假设你有一个字符串列表如下:
>>> l = ['Test id_g001','**Test id_g002','Test id_g000', 'Value_is_0', 'Value_is_2', 'Value_is_1']
你想根据ID和Value的值对它们进行排序,然后就可以这样做:
>>> from operator import itemgetter
>>> sorted(l, key=itemgetter(-1))
['Test id_g000', 'Value_is_0', 'Test id_g001', 'Value_is_1', '**Test id_g002', 'Value_is_2']
