# How to fix “TypeError: ‘str’ object cannot be interpreted as an integer”

If you are getting trouble with the error “TypeError: ‘str’ object cannot be interpreted as an integer”, do not worry. Today, our article will give a few solutions and detailed explanations to handle the problem. Keep on reading to get your answer.

## Why does the error “TypeError: ‘str’ object cannot be interpreted as an integer” occur?

TypeError is an exception when you apply a wrong function or operation to the type of objects. “TypeError: ‘str’ object cannot be interpreted as an integer” occurs when you try to pass a string as the parameter instead of an integer. Look at the simple example below that causes the error.

Code:

myStr = "Welcome to Learn Share IT"

for i in range(myStr):
print(i)

Result:

Traceback (most recent call last)
in <module>
----> 3 for i in range(myStr):
TypeError: 'str' object cannot be interpreted as an integer

The error occurs because the range() function needs to pass an integer number instead of a string.

Let’s move on. We will discover solutions to this problem.

## Solutions to the problem

### Traverse a string as an array

A string is similar to an array of strings. As a result, when you want to traverse a string, do the same to an array. We will use a loop from zero to the length of the string and return a character at each loop. The example below will display how to do it.

Code:

myStr = "Welcome to Learn Share IT"

for i in range(len(myStr)):
print(myStr[i], end=' ')

Result:

W e l c o m e   t o   L e a r n   S h a r e   I T 

### Traverse elements

The range() function is used to loop an interval with a fix-step. If your purpose is traversing a string, loop the string directly without the range() function. If you do not know how to iterate over all characters of a string, look at our following example carefully.

Code:

myStr = "Welcome to Learn Share IT"

for i in myStr:
print(i, end=' ')

Result:

W e l c o m e   t o   L e a r n   S h a r e   I T 

### Use enumerate() function

Another way to traverse a string is by using the enumerate() function. This function not only accesses elements of the object but also enables counting the iteration. The function returns two values: The counter and the value at the counter position.

Code:

myStr = "Welcome to Learn Share IT"

for counter, value in enumerate(myStr):
print(value, end=' ')

Result:

W e l c o m e   t o   L e a r n   S h a r e   I T 

You can also get the counter with the value like that:

myStr = "Welcome to Learn Share IT"

for counter, value in enumerate(myStr):
print(f"({counter},{value})", end= ' ')

Result:

(0,W) (1,e) (2,l) (3,c) (4,o) (5,m) (6,e) (7, ) (8,t) (9,o) (10, ) (11,L) (12,e) (13,a) (14,r) (15,n) (16, ) (17,S) (18,h) (19,a) (20,r) (21,e) (22, ) (23,I) (24,T)
