# Find Index of Shortest & Longest String in List in Python (Example)

Hi! This tutorial will show you how to get the index of the shortest and longest strings in list in the Python programming language.

Here is an overview:

Let’s dive into the Python code!

## Create Sample List of Strings

Here, we will create the sample Python list of strings that we will use in the example in this tutorial. So, in your preferred Python coding IDE, run the line of code below to create the sample list of strings:

```my_list = ["chair", "wardrobe", "stool", "bed"]

print(my_list)

# ['chair', 'wardrobe', 'stool', 'bed']

print(type(my_list))

# <class 'list'>```

With the sample list of strings created, let us now see how to determine the index of the shortest and longest strings in the list.

## Example: Get Index of Shortest & Longest String Using For Loop, min(), max() & enumerate()

In this example, we will demonstrate how to use a for loop, the min() function, the max() function, and the enumerate() function to return the index of the shortest and longest strings in the list. Run the script below:

```# get length of each string in list
length = []
for i in range(len(my_list)):
length.append(len(my_list[i]))

# get index of shortest string
for i,j in enumerate(length):
if j == min(length):
print(f"The index of the shortest string is {i}")

# get index of longest string
for i,j in enumerate(length):
if j == max(length):
print(f"The index of the longest string is {i}")

# The index of the shortest string is 3
# The index of the longest string is 1```

What we did in the above example is very simple. First, we determined the length of individual strings in the list, by running a loop through the list, and parsing that to the len() function, which then returned a list containing the length of each string in the list.

Next, to get the length of the shortest and longest string, we ran for loops through the output of `enumerate(length)`, which is a list of tuples containing the values and their respective index positions. We then used a conditional statement to return the index number (i) when the value (j) is equal to the `min(length)` for shortest string, and `max(length)` for longest string.

## Define a Function for Easy Code Reusability

For easy reusability of the code on other string lists, it is best to define a function that is called only when it is needed, instead of having to rewrite the code each time, which is rather tedious. In the script below, we will define a function that will run our code above whenever the function is called:

```def getIndex(data):

length = []
for i in range(len(data)):
length.append(len(data[i]))

for i,j in enumerate(length):
if j == min(length):
print(f"The index of the shortest string is {i}")

for i,j in enumerate(length):
if j == max(length):
print(f"The index of the longest string is {i}")```

The script is basically the same. The only differences you would notice are the `def` keyword, which stands for “define”, and the function name `getIndex()` wherein we specified a parameter, or argument, `data`. With this, if a new string list is parsed to this function, it takes the place of the argument “data” anywhere it appears in the code.

Let us try out our new function on another string list:

```new_list = ["aeroplane","ship", "bus", "train"]

getIndex(data = new_list)

# The index of the shortest string is 2
# The index of the longest string is 0```

With that, we have demonstrated how to find the shortest and longest string index in a list in Python. I do hope you found this tutorial helpful!
