combine list of lists python
x = [["a","b"], ["c"]]
result = sum(x, [])
# This combines the lists within the list into a single listcombine list of lists python
x = [["a","b"], ["c"]]
result = sum(x, [])
# This combines the lists within the list into a single listpython merge lists
# Basic syntax:
first_list.append(second_list) # Append adds the the second_list as an
# element to the first_list
first_list.extend(second_list) # Extend combines the elements of the
# first_list and the second_list
# Note, both append and extend modify the first_list in place
# Example usage for append:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.append(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, [6, 7, 8, 9]]
# Example usage for extend:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.extend(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, 6, 7, 8, 9]python concatenate lists
a = [1, 2, 3]
b = [4, 5]
# method 1:
c = a + b # forms a new list with all elements
print(c) # [1, 2, 3, 4, 5]
# method 2:
a.extend(b) # adds the elements of b into list a
print(a) # [1, 2, 3, 4, 5]add two list in python
list1 = ["a", "b" , "c"]
list2 = [1, 2, 3]
list1.extend(list2)
print(list1)python merge list of lists
flat_list = [item for sublist in t for item in sublist]merge two lists python
>>> l1 = [1, 2, 3]
>>> l2 = [4, 5, 6]
>>> joined_list = [*l1, *l2] # unpack both iterables in a list literal
>>> print(joined_list)
