Overview

The char.chararray.dump() method in Python is used to dump a pickle of an input array to a specified file. The input array can be read back with pickle.load.

Syntax

char.chararray.dump(file)
Syntax for the char.chararray.dump() method

Parameter value

The char.chararray.dump() method takes file as the parameter value which represents the string name for the dump file.

Code

Let's look at the code below:

import numpy as np
# creating an array
myarray = np.array(['aAaAaA', ' aA ', 'abBABba'])
# creating a dump file
myfile="myfile"
# implementing the char.chararray.dump() method
myarray.dump(myfile)
# to read the array back
print(np.load)
Implementing the char.chararray.dump() method

Explanation

  • Line 1: We import the numpy module.
  • Line 4: We create an array myarray() using the array() function.
  • Line 7: We create a dump file for the array, myfile.
  • Line 10: We implement the char.chararray.dump() method on the array.
  • Line 13: We use pickle.load to read back the path for the array.
