Charley-December 23rd, 2020 at 7:54 am none Comment author #40541 on Convert list to string in python using join() / reduce() / map() by thispointer.com The string looks for example the following: {"1,2,3,5,10,12,13,17,26,30,32,41,42,43,113,115,121,125"} Mathematica sees this as one string, this is important, not as a list of strings. I wanted to see if my personal phone number could be converted into something like "999-9999-BEAR." Method #2 : Using map() + split() + list() Since the drawback of above method is that the conversion doesn’t change the datatype of the unit numbers, so if it’s desired to change the data type of number as well, it is suggested to additionally use map() to have list of strings as integers. Probably not the best way but it works for what I need it for. This Python program allows the user to enter any positive integer. For example, if the input number is 1234 then the output would be 1+2+3+4 = 10 (sum of digits). int(390.8) In this case, 390.8 will be converted to 390.
