Question

Right I am a complete beginner here, trying to work through various python tutorials and a lot of them are great. However none of them have much of a consolidated approach to learning, where one skill builds on another. They all seem to show you things in silo. All I am trying to do is concatenate a string with an integer that is held in an array. Here is the code:

text = 'product_price_'
numberArray = [1,2,3,4,5,6,7,8,9,10]


for i in numberArray:
  print text + str(numberArray[i])

This kind of works, giving me the result:

product_price_2
product_price_3
product_price_4
product_price_5
product_price_6
product_price_7
product_price_8
product_price_9
product_price_10
Traceback (most recent call last):
  File "/Users/me/Documents/Programming/python/eclipse/workspace/concat.py", line 8, in <module>
print text + str(numberArray[i])
IndexError: list index out of range

Like I say this is really simple stuff. I can concatenate, I can print an array but do both??

Can anyone plug this gap in my knowledge for me?

Thanks

Answer 1

i contains the value from the array, not the index. So if you want to concatenate the value, try this:

for i in numberArray:
  print text + str(i)
