split string using to words using the empty spaces and storing them in a list using python

for example i have this string : ch = “promotion bac 2019” and an empty list : t=[] i want to make the list get each word separately using the empty spaces result will be : t=[“promotion”,”bac”,”2019″] i tried deleting each word from the string after storing it in the list but i didn’t work properly . dont mind looking at my code its really bad

def splitword (ch,t):
    i=0
    while len(ch)!=-1:
            if ch[i]== " " :
                t.append(ch[0:i])
                ch=ch.replace(ch[0:i],"")
            else : 
                i=i+1 
            
t=[]
ch = "promotion bac 2019"
splitword (ch,t)
print(t)

Answer

here the fixes for your code

def splitword (ch,t): 
     i=0 
     while i != len(ch): 
         if ch[i]== " " : 
             t.append(ch[0:i]) 
             ch=ch.replace(ch[0:i+1],"") # need to add 1 for the end position
             i = 0  # reset position
         else :  
             i=i+1
     if ch:  
        t.append(ch)  # add the last word
t=[] 
ch = "promotion bac 2019" 
splitword (ch,t) 
print(t)

But from my side of view the @Sayse has gave you good advice about the split function.
