NumPy: Create an array with 10^3 elements
Create Array with 10^3 Elements
Write a NumPy program to create an array with 10^3 elements.
Sample Solution:
Python Code:
# Importing the NumPy library and aliasing it as 'np'
import numpy as np
# Creating an array 'x' using NumPy's arange function to generate numbers from 0 to 999 (inclusive)
x = np.arange(1e3)
# Printing the array 'x' containing numbers from 0 to 999
print(x)
Sample Output:
[ 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. 35 . 36. 37. 38. 39. 40. 41. 42. 43. 44. 45. 46. 47 . 48. 49. 50. 51. 52. 53. 54. 55. 56. 57. 58. 59 . 60. 61. 62. 63. 64. 65. 66. 67. 68. 69. 70. 71 . 72. 73. 74. 75. 76. 77. 78. 79. 80. 81. 82. 83 . 84. 85. 86. 87. 88. 89. 90. 91. 92. 93. 94. 95 .............................. 900. 901. 902. 903. 904. 905. 906. 907. 908. 909. 910. 911 . 912. 913. 914. 915. 916. 917. 918. 919. 920. 921. 922. 923 . 924. 925. 926. 927. 928. 929. 930. 931. 932. 933. 934. 935 . 936. 937. 938. 939. 940. 941. 942. 943. 944. 945. 946. 947 . 948. 949. 950. 951. 952. 953. 954. 955. 956. 957. 958. 959 . 960. 961. 962. 963. 964. 965. 966. 967. 968. 969. 970. 971 . 972. 973. 974. 975. 976. 977. 978. 979. 980. 981. 982. 983 . 984. 985. 986. 987. 988. 989. 990. 991. 992. 993. 994. 995 . 996. 997. 998. 999.]
Explanation:
The above code creates and prints a NumPy array with 1000 elements, ranging from 0 to 999.
x = np.arange(1e3): This line creates a 1D NumPy array with elements from 0 to 999 (1e3 is scientific notation for 1000). The np.arange() function generates an array of evenly spaced values within the specified range.
print(x): This line prints the created NumPy array ‘x’ containing the values from 0 to 999.
