I'm trying to append to a list in Python 3 but want to do this in the shortest amount of lines possible. In order to do this, I have created a blank 1D array and used basic iteration to append to it. I want to append the 2d array within the iteration as well as allowing the user to be able to input their data to the 2d arrays. I know the code below doesn't work. However, I wanted to know if this is possible to achieve?
I'd like the output to be like the following:
[First name, Second name], [First name, Second name], [First name, Second name]
Array = []
for i in range (0,4):
Array.append([input("First name")][input("Second name")])
print(Array)
Your question is a bit unclear. I understand that you want the output as:
[['Aaron', 'Armstrong'],['Barry', 'Batista'], ['Cindy', 'Wilson']]
And that you want least number of lines as possible, so this is how short I was able to make it using List Comprehension:
Array = [[input("First Name: "), input("Last Name: ")] for _ in range(4)]
print(Array)
Or make it one line with :
print([[input("First Name: "), input("Last Name: ")] for _ in range(4)])
Your code seems wrong, it's unclear what you want to do.
I'm assuming you want a list like :
[
["Mark", "Wahlberg"],
["Matt", "Damon"]
]
you can do that like :
num_names = 5
name_arr = []
for i in range(num_names):
temp_arr = list(input("Enter name space separated: ").split(" "))
name_arr.append(temp_arr)
Enter your name like : "Matt Damon", it splits it into 2 strings and creates a list.
