I have a small project in Python 3.8 and I want to get some Item from an array:
listArr = ["physics", "chemistry", "mathematics", "english"]
itemResult = "1"
subject = listArr[itemResult]
print(subject)
But I got an error: TypeError: list indices must be integers or slices, not str
Traceback (most recent call last):
File "main.py", line 3, in <module>
print(listArr[itemResult])
TypeError: list indices must be integers or slices, not str
How can I solve this issue?

Index of an array must be integer, It's not allow string value, so you can cast as bellow:
listArr = ["physics", "chemistry", "mathematics", "english"] itemResult = int("1") print(listArr[itemResult]) # output chemistryHope it is useful for you.
