Hello you guys, I am a newbie in Python and I'm also studying more about Python.
I have some like code, I created an array of cars and I want to get first item of that array, I access by index. Function as below:
cars = ['Camry'], ['Lambogini'], ['Mazda CX'], ['Land Rover']
print("I choose the " + cars[0] + " if I have enough money to buy it.")
But I get an exception TypeError: can only concatenate str (not "list") to str when I run code above.
Traceback (most recent call last):
File "main.py", line 3, in <module>
print("I choose the " + cars[0] + " if I have enough money to buy it.")
TypeError: can only concatenate str (not "list") to str
And I am using python 3.8.2
Anyone can explain it to me? How can I solve it?
Thanks for any response.
Have 2 answer(s) found.

You need to convert
cars[0]to string by usingstr()method. See like this:cars = ['Camry'], ['Lambogini'], ['Mazda CX'], ['Land Rover'] print("I choose the " + str(cars[0]) + " if I have enough money to buy it.")#Output
I choose the ['Camry'] if I have enough money to buy it. -

You created a typle of list so you can not access directly by index, you can use str() method to help convert tuply to string.
print("I choose the " + str(cars[0]) + " .....")Or you can declare your array is string only, not typle of list. For an example:
cars = ['Camry', 'Lambogini', 'Mazda CX', 'Land Rover'] print("I choose the " + cars[0] + " if I have enough money to buy it.")And output:
I choose the Camry if I have enough money to buy it.I hope it clear for you.
