# Compare and return True if an array is greater than another array in Numpy

To compare and return True if an array is greater than another array, use the numpy.char.greater() method in Python Numpy.

NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. It supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse array libraries.

## Steps

At first, import the required library −

import numpy as np

Create two One-Dimensional arrays of string −

arr1 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa'])
arr2 = np.array(['Cio', 'Tom', 'Cena', 'Kate', 'Adams', 'brad', 'aa'])

Display the arrays −

print("Array 1...", arr1)
print("Array 2...", arr2)

Get the type of the arrays −

print("Our Array 1 type...", arr1.dtype)
print("Our Array 2 type...", arr2.dtype)

Get the dimensions of the Arrays −

print("Our Array 1 Dimensions...",arr1.ndim)
print("Our Array 2 Dimensions...",arr2.ndim)

Get the shape of the Arrays −

print("Our Array 1 Shape...",arr1.shape)
print("Our Array 2 Shape...",arr2.shape)

To compare and return True if an array is greater than another array, use the numpy.char.greater() method in Python Numpy. The arr1 and arr2 are the two input string arrays of the same shape −

print("Result...",np.char.greater(arr1,arr2))


## Example

import numpy as np

# Create two One-Dimensional arrays of string
arr1 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa'])

# Display the arrays
print("Array 1...", arr1)
print("Array 2...", arr2)

# Get the type of the arrays
print("Our Array 1 type...", arr1.dtype)
print("Our Array 2 type...", arr2.dtype)

# Get the dimensions of the Arrays
print("Our Array 1 Dimensions...",arr1.ndim)
print("Our Array 2 Dimensions...",arr2.ndim)

# Get the shape of the Arrays
print("Our Array 1 Shape...",arr1.shape)
print("Our Array 2 Shape...",arr2.shape)

# To compare and return True if an array is greater than another array, use the numpy.char.greater() method in Python Numpy
# The arr1 and arr2 are the two input string arrays of the same shape.
print("Result...",np.char.greater(arr1,arr2))

## Output

1

Our Array 2 Dimensions...
1

Our Array 1 Shape...
(7,)

Our Array 2 Shape...
(7,)

Result...
