expand_more Numpy's join(~) method returns a Numpy array of strings where a string in the first array is inserted between every two adjacent characters of a string the second array. Check the examples for clarification.
Parameters
1. sep | array-like
A string used to separate seq.
2. seq | array-like
A sequence of strings that are to be separated.
Return value
A Numpy array of strings.
Examples
To separate "abfee" using "*" and "cd" using "**":
np.char.join(["*", "**"], ["abfee", "cd"])
array(['a*b*f*e*e', 'c**d'], dtype='<U9')
If the seq strings are less than two characters, the original string is returned:
np.char.join(["*", "**"], ["", "c"])
array(['', 'c'], dtype='<U1')
