Numpy n dimensional Arrays ( ndarray )

Axis of Two dimensional array Numpy is used scientific computing with Python.
We can create powerful multidimensional arrays in numpy. Numpy requires all elements are to be of same data type. ( This is one of the main difference with Pandas which can accommodate different data types. ) After installation you can add this line to include Numpy in your program.
import numpy as np
Getting the version
import numpy as np
print("Numpy Version : ",np.__version__)

Array MethodsMethods to get result ( output ) using NumPy
array_split()break the array to get sub-arrays
bincountfrequency of occurrence of elements
whereReturn elements depending on condition check
shapeReturn shape of the array
reshapeChange the array shape and dimension

Creating array

createCreating array using Numpy
eyearray with ones and zeros
emptyarray without initializing entries
empty_likearray of same shape and type
fullAray filled with input value
onesarray filled with ones
arangecreating array of fixed steps
linspacecreating array of fixed number
zerosAray filled with zeros
ExerciseCreating different types of array

random.randitRandom integers with lower and upper limits and size
random.randUniform distribution [0,1] of random numbers of given shape & population
random.randnNormal distribution of random numbers of given shape & population
random_sampleContinuous uniform distribution over an interval


sum()Sum of elements, or along the axis
mean()Mean value of elements, or along the axis
max()Maximum value among elements, or along the axis
min()Minimum value among elements, or along the axis
std()Standard deviation along the axis

Get the list of all functions of Pandas. ( Use dir() )
import numpy as np
print(len(dir(np))) # 622
List of functions
for i in dir(np):
    print(i)
