# How to Find the Shortest String in a NumPy Array?

## Python Shortest String in NumPy Array

To find the shortest string in a given NumPy array, say `arr`, you can use the `min(arr, key=len)` function that determines the minimum by comparing the length of the array elements using the `len()` function as a key for comparison.

```import numpy as np

arr = np.array(['Alice', 'Bob', 'Carl'])
print(min(arr, key=len))
# Bob
```

## Python Length of Shortest String in NumPy Array

To find the length of the shortest string in a NumPy array `arr`, use the `min(arr, key=len)` function to obtain the string with the minimum length and then pass this min string into the `len()` function to obtain the number of characters.

`len(min(arr, key=len))`

Here’s a more detailed code example of a simple 1D NumPy Array:

```import numpy as np

arr = np.array(['Alice', 'Bob', 'Carl'])

# Print Shortest String:
print(min(arr, key=len))
# Bob

# Print Length of Shortest String
print(len(min(arr, key=len)))
# 3
```

## Get Shortest String from NumPy Axis (2D, Column or Row)

To get the shortest string from a certain NumPy array axis (e.g., row or column), first use simple NumPy slicing and indexing to get that axis (e.g., `arr[0, :]` to get the first row) and pass it into the `min()` function with the `key` argument set to the length function like so: `min(arr[0, :], key=len)`.

Here’s an example to get the shortest string of the first row of a 2D array:

```import numpy as np

arr = np.array([['Alice', 'Bob', 'Carl'],
['Ann', 'Zoe', 'Leonard']])

print(min(arr[0, :], key=len))
# Bob
```

Here’s an example to get the shortest string of the third column of a 2D array:

```print(min(arr[:, 2], key=len))
# Carl```

You get the idea. 🙂

If you want to get the shortest string from the whole NumPy array, not only from a column or row or axis, first flatten it and then pass the flattened array into the `min()` function using the `key=len` argument.
