I am trying to make a loop pulling from multiple arrays-CodePudding

I am making a simple calculator that, among other things, can provide the user with a formatted history of their previous computations.

 print('Formmated as an equation')
 for x in range(len(finalhistory)):
    print(num1history(x)   float(operationHistory(x))   num2history(x)   ' = '   
    finalhistory(x))
    print(' ')
 return

When ever this is run though, I get an error saying:

Exception has occurred: TypeError
'list' object is not callable
 File "MCT.py", line 34, in BH
    print(num1history(x)   operationHistory(x)   num2history(x)   ' = '   finalhistory(x))

Edit: Should have clarified that the histories called are arrays. num1history, num2history, finalhistory store float values, and operationHistory stores str values.

CodePudding user response：

You index lists with square brackets

 print('Formmated as an equation')
 for x in range(len(finalhistory)):
    print(f'{num1history[x]}   {float(operationHistory[x])}   {num2history[x]}    =    
    {finalhistory[x]}')
    print(' ')
 return

You should also print with an f-string

CodePudding user response：

finalhistory is a list. We can't call this like a function.

finalhistory(x) -> is the error.

Same for num1history, operationHistory and num2history

You might intent to use finalhistory[x], num1history[x], operationHistory[x], num2history[x].

CodePudding user response：

As I can see from the code you are using a list and lists are not callable. Solution: Use finalhistory[x]...similarly for other arrays
