comprehension for loop python code example
Example 1: python list comprehension
#example: removing common elements found in `a` from `b`.
a = [1,2,3,4,5]
b = [5,6,7,8,9]
# desired output: [1,2,3,4]
# gets each item found in `a` AND not in `b`
print([i for i in a if i not in b])
Example 2: list comprehension python one line
doubled_odds = [n * 2 for n in numbers if n % 2 == 1]
Example 3: list comprehension for loop
matrix = [[1, 2], [3,4], [5,6], [7,8]]
transpose = [[row[i] for row in matrix] for i in range(2)]
print (transpose)
