``parse_int``, if specified, will be called with the string of every JSON int to be decoded. By default this is equivalent to int(num_str). This can be used to use another datatype or parser for JSON integers (e.g. float). ``parse_constant``, if specified, will be called with...

# Join string with character str3 = ",".join(str1) print(str3) # Join string with another string # Join strings str3 = str1.join(str2) print(str3) # Output: # A,B,C # XABCYABCZ 3. Join List of Strings Using the list of strings as an argument to the python str.join() ...
You can also convert the string to a list usingstring slicing. It initializes a string and defines a functionConvert()to perform the conversion. In theConvert()function, an empty listmylistis created. Then, the slicemylist[:0]is used to insert each character from the stringstringat the ...
