python sort list in list code example

Example 1: how do i sort list in python

my_list = [9, 3, 1, 5, 88, 22, 99]

# sort in decreasing order
my_list = sorted(my_list, reverse=True) 
print(my_list)

# sort in increasing order
my_list = sorted(my_list, reverse=False) 
print(my_list)

# another way to sort using built-in methods
my_list.sort(reverse=True)  
print(my_list)

# sort again using slice indexes
print(my_list[::-1])

# Output
# [99, 88, 22, 9, 5, 3, 1]
# [1, 3, 5, 9, 22, 88, 99]
# [99, 88, 22, 9, 5, 3, 1]
# [1, 3, 5, 9, 22, 88, 99]

Example 2: sort a list according to location

LonLat myHouse = /* whatever */ ;
Comparable comp = new Comparable () {
    LonLat a;
    int compareTo (Object b) {
        int aDist = calcDistance(a, myHouse) ;
        int bDist = calcDistance(b, myHouse) ;
        return aDist - bDist;
    }
};
myLonLatList.sort(lonLatList, comp);
