Do different versions of python handle indexing differently?-CodePudding

python 3.10.4 Ubuntu 20.04 running python 3.10.4 spyder IDE Python 3.9.12 64-bit | Qt 5.9.7 | PyQt5 5.9.2 | Linux 5.15.0-47-generic

My python version in ubuntu and spyder are different. Does this cause the following problems?

I've run into two separate incidents on two separate sites where my IDE produced a different output to the one i the example.

B) This other website states that the following code:

fruits = ["apple", "grape", "orange", "guava", "banana"]
 
#Printing out the indexes of Apples and Banana
print("Indedx of Apple: "   fruits.index("apple"))
print("Indedx of Banana: "   fruits.index("banana"))

will produce the output: Indedx of Apple: 0 Indedx of Banana: 4

However, my IDE returns:

TypeError: can only concatenate str (not "int") to str

I made an error with question A and have removed it

CodePudding user response：

No, different versions of Python/IDEs/operation systems do not handle indexing differently.

For (A), please double check that you have not made some mistake when copying the code. For a start, it seems very unlikely that you are getting wor because wor is not even in the original string. Do you mean Wor? Is it possible that you missed the final !?

For (B), the website you copied from is wrong. Try the following:

fruits = ["apple", "grape", "orange", "guava", "banana"]

#Printing out the indexes of Apples and Banana
print("Indedx of Apple: "   str(fruits.index("apple")))
print("Indedx of Banana: "   str(fruits.index("banana")))
