So, try calling find() without trying to specify beg and end as keyword (e.g. named as you've done) arguments. Also read up on keyword arguments (and arguments in general): http://docs.python.org/release/1.5.1p1/tut/keywordArgs.html Walter ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Your traceback message gives you the reason it's not working, `find()
takes no keyword arguments`. The function only takes positional
arguments so if you just write `astr.find(str1, 0, 3)` it will work as
you expect it to.
help(''.find)
Help on built-in function find:
find(...)
S.find(sub [,start [,end]]) - int
Return the lowest index in S where substring sub is found,
such that sub is contained within s[start:end]. Optional
arguments start and end are interpreted as in slice notation.
Return -1 on failure.

Fortunately this is simple enough to fix: astr = foobar str1 =foo astr.find(str1, beg=0, end=3) Please take more care to post code in PLAIN TEXT, not html rich text, which may mangle line breaks and break the code.

This same problem with find() Could you please help me! Did you read the error message? find() takes no keyword arguments This means just what it says: the find method does not take keyword arguments. Do you understand what keyword arguments are? # Wrong, will not work: astr.find(str1, begin=23, end=42) # Right, will work: astr.find(str1, 23, 42) -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
