I want to do this to 2 different lists consisting of strings-CodePudding

I want to do this to 2 different lists consisting of strings with:

list_A = ['Krish', 'Ram', 'Rajaa']
list_B = ['Sweet', 'Joy', 'Discipline']

I've written:

def Srinivasaragavansir(x,y):
     out= x[0].upper()   x[1:]   " "   y[0].upper()   y[1:]
     return(out)

When I run Srinivasaragavansir(list_A,list_B) I get:

TypeError: can only concatenate str (not "list") to str

CodePudding user response：

so here the answer the things you are doing is you are adding string to to the list. ex x[0].upper() this return string and x[1:] and this return list so here you are adding list two string which is wrong.

if you wana add then you can add list together x[1:] y[1:] ['Ram','Rajaa''Joy','Discipline] and to add string together x[0].upper() " " y[0].upper() "KRISH SWEET" you can solve it in this way

This should work you i guess

import functools
def Srinivasaragavansir(x, y):
    out1 = functools.reduce(lambda i,j: str(i)   ' '   str(j),x[1:],x[0].upper())
    out2 = functools.reduce(lambda i, j: str(i)   ' '   str(j), y[1:], y[0].upper())
    out = out1   ' '   out2
    return out
list_A = ['Krish', 'Ram', 'Rajaa']
list_B = ['Sweet', 'Joy', 'Discipline']
print(Srinivasaragavansir(list_A,list_B))
