AttributeError: ‘str’ object has no attribute ‘reverse’ – How to solve it?

The error AttributeError: ‘str’ object has no attribute ‘reverse’ in Python occurs if you use reverse() method in the string. Follow the article to learn how to handle it.

When does the AttributeError: ‘str’ object has no attribute ‘reverse’ in Python occur?

The AttributeError: ‘str’ object has no attribute ‘reverse’ in Python occurs when we use the call reverse() method in the string but the string is not accessible to the reverse() method. Follow the code below to better understand.

Code example:

# Initialize a variable str store string
str  = "learn share IT"

print(str.reverse())

Output:

AttributeError: 'str' object has no attribute 'reverse'

I will show you the most straightforward solutions to fix this error, according to the solution below.

The solution to fix this error

Using the For-Loop

Here, I will create a reverse_string() function to reverse a string using for – loop to go through all the elements in the string. 

Next, we need to create variable str to store the string we need to reverse. For each element we pass, the string str will be updated by taking the passing element plus str. See the code example below.

Code example:

# The reverse() function you create by for - loop
def reverse_string(mystr):
    str = ""
    for i in mystr:
        str = i + str
    return str

# Initialize a variable store my string
mystr = "learn share IT"

print("The original my string is: ", end="")
print(mystr)
print("The reversed my string is: ", end="")
print(reverse_string(mystr))

Output:

The original my string is: learn share IT
The reversed my string is: TI erahs rnael

Using an extended slice

In this solution, we use an extended slice, which offers to add a “step” field as str[start, stop, step], and if no field is provided for start or stop, the default values are 0, and the length of the string, respectively. A value of “-1” indicates that a string should start at the end and stop at the beginning, which would reverse it.

Code example:

# Function to reverse a string
def reverse_string(str):
    str = str[::-1]
    return str

# Initialize a variable
str = "learn share IT"

print("The original my string is : ", end="")
print(str)

print("The reversed my string is : ", end="")
print(reverse_string(str))

Output:

The original my string is : learn share IT
The reversed my string is : TI erahs nrael
