Does anyone know what code to use when you need to replace a certain number of digits/numbers in a string?

Heya @austere robin 👋
You're probably looking at re.sub() or str.replace() (renamed as Reptile's examples are better :P)
If you can give some examples of what needs to be done..?

Uh, depends on what you mean by "replace a certain number of digits/numbers", but str.replace and re.sub come to mind.

I've been trying to use something like this: r = r.replace([:S])

I'm not sure what that's meant to mean, but replace has an argument to limit the max number of replacements, if that's what you want.

!d str.replace

str.replace 

str.replace(old, new[, count])```
Return a copy of the string with all occurrences of substring *old* replaced by *new*. If the optional argument *count* is given, only the first *count* occurrences are replaced.

I don't think replace is actually what you want

#

You are just trying to remove a beginning part?

Flip your slice around

#

And assign that slice back to your variable

austere robin
#

like this? R1 = slice(r[:S])

jaunty tulip
#

The colon notation in [] is a slice (when used as getitem)

#

And you need to flip it around: the stop value should be the start value

austere robin
#

so like this? r = r.replace([S:])

jaunty tulip
#

Try to not guess
