Changing up a code from changing a single letter to changing a word?

Question

How Would I change this function from changing only the letters to change the entire word? I believe I have to change the ch in the code (for ch in newString: ) but I don't know what to.

replacements = {
'TOMORROW': 'TMR',
'ABOUT': 'BOUT',
'PLEASE': 'PLZ',
'BEFORE': 'B4'
}

def replace(newString):
old,new = [],[]
for ch in newString:
    if replacements.get(ch):
        newString = newString.replace(ch, replacements.get(ch))
    print(newString)

You can simply split the string on space and it will be easy then

replacements = {
'TOMORROW': 'TMR',
'ABOUT': 'BOUT',
'PLEASE': 'PLZ',
'BEFORE': 'B4'
}

st="ABOUT last BEFORE"
li=st.split()
for i in range(len(li)):
    if li[i] in replacements:
        li[i]=replacements[li[i]]
print(" ".join(li))

You can do something like this:

replacements = {
'TOMORROW': 'TMR',
'ABOUT': 'BOUT',
'PLEASE': 'PLZ',
'BEFORE': 'B4'
}

message="ABOUT TOMORROW PLEASE SEE ME BEFORE NOON"

for word, initial in replacements.items():
    message = message.replace(word, initial)
print(message)   #--> "BOUT TMR PLZ SEE ME B4 NOON"

or backwards:

message="BOUT TMR PLZ SEE ME B4 NOON"
for word, initial in replacements.items():
    message = message.replace(initial, word)
print(message)  #--> "ABOUT TOMORROW PLEASE SEE ME BEFORE NOON"
