[Numpy] array

Numpy

: Numerical Python

 

 

array1 = numpy.arange(2, 7)
print(array1)​

import numpy

array1 = numpy.array([2,3,5,7,11,13,17,19,23,29,31])
array2 = numpy.array([[1,2,3,4], [5,6,7,8], [9,10,11,12]])

print(type(array1))
print(array1.shape)
print(array1.size)

print(type(array2))
print(array2.shape)
print(array2.size)

 

 

결과

 

full

array1 = numpy.full(6, 7)
    
print(array1)
# [7 7 7 7 7 7]

array1 = numpy.full(6, 1)
array2 = numpy.ones(6, dtype=int)
    
print(array1)
print()
print(array2)
#[1 1 1 1 1 1]

#[1 1 1 1 1 1]

 

zeros

array1 = numpy.full(6, 0)
array2 = numpy.zeros(6, dtype=int)
    
print(array1)
print()
print(array2)

 

 

arange

array1 = numpy.arange(6)
print(array1)
array1

# 출력
# [0 1 2 3 4 5]
# array([0, 1, 2, 3, 4, 5])

array1 = numpy.arange(2, 7)
print(array1)

# [2 3 4 5 6]

array1 = numpy.arange(3, 17, 3)
print(array1)

# [ 3  6  9 12 15]

 

끝 출력 숫자 -1 만큼
