Error: ‘int’ object is not subscriptable – Python

Error: ‘int’ object is not subscriptable – Python :

When you type x = 0 that is creating a new int variable (name) and assigning a zero to it.

When you type x[age1] that is trying to access the age1‘th entry, as if x were an array.


The problem is in the line,

int([x[age1]])

What you want is

x = int(age1)

You also need to convert the int to a string for the output…

print "Hi, " + name1+ " you will be 21 in: " + str(twentyone) + " years."

The complete script looks like,

name1 = raw_input("What's your name? ")
age1 = raw_input ("how old are you? ")
x = 0
x = int(age1)
twentyone = 21 - x
print "Hi, " + name1+ " you will be 21 in: " + str(twentyone) + " years."

When you write x = 0x is an int…so you can’t do x[age1] because x is int


‘int’ object is not subscriptable is TypeError in Python. To better understand how this error occurs, let us consider the following example:

list1 = [1, 2, 3]
print(list1[0][0])

If we run the code, you will receive the same TypeError in Python3.

TypeError: 'int' object is not subscriptable

Here the index of the list is out of range. If the code was modified to:

print(list1[0])

The output will be 1(as indexing in Python Lists starts at zero), as now the index of the list is in range.

1

When the code(given alongside the question) is run, the TypeError occurs and it points to line 4 of the code :

int([x[age1]])

The intention may have been to create a list of an integer number(although creating a list for a single number was not at all required). What was required was that to just assign the input(which in turn converted to integer) to a variable.

Hence, it’s better to code this way:

name = input("What's your name? ")
age = int(input('How old are you? '))
twenty_one = 21 - age
if(twenty_one < 0):
    print('Hi {0}, you are above 21 years' .format(name))
elif(twenty_one == 0):
    print('Hi {0}, you are 21 years old' .format(name))
else:
    print('Hi {0}, you will be 21 years in {1} year(s)' .format(name, twenty_one))

The output:

What's your name? Steve
How old are you? 21
Hi Steve, you are 21 years old
