## Simple without stride and slice
print(y[1,2])

#[Output]:
#9

## Using ":" will go from start to end

## Without stride
print("This is without stride-:")
print(y[:])

print("\n")

## With stride
print("This is with the stride of 3-:")
print(y[::3])

#[Output]:
#This is without stride-:
#[[ 0  1  2  3  4  5  6]
# [ 7  8  9 10 11 12 13]
# [14 15 16 17 18 19 20]
# [21 22 23 24 25 26 27]
# [28 29 30 31 32 33 34]]

#[Output]:
#This is with the stride of 3-:
#[[ 0  1  2  3  4  5  6]
# [21 22 23 24 25 26 27]]


## It will extract rows from 1 to 4 and for all columns
print(y[1:5,:])

#[Output]:
#[[ 7  8  9 10 11 12 13]
# [14 15 16 17 18 19 20]
# [21 22 23 24 25 26 27]
# [28 29 30 31 32 33 34]]


## If we want to choose particular columns

print(y[1:5:2,::3])

#[Output]:
#[[ 7 10 13]
# [21 24 27]]
