Sorting method when python list elements are tuples

The following is a sorting method for everyone to share a python list element when it is a tuple. It has a good reference value and I hope it will be helpful to everyone. Come and take a look together

As shown below:

dist = [('m',5),('e',4),('c',9),('d',1)]
dist.sort(key= operator.itemgetter(0))
print(dist)

dist = [('m',5),('e',4),('c',9),('d',1)]
dist.sort(key= lambda k:k[0])
print(dist)

① When key=operator.itemgetter(0), the first element of the tuple is taken for comparison.

② When key=operator.itemgetter(1), the second element of the tuple is taken for comparison.

key=lamda k:k[0 or 1] Similarly
