Python Little Goal 6

Python day 12

Today we will work with the character strings in Python a little bit.

1.Swap Case 

The task is to swap cases. Convert all lowercase letters to uppercase letters and vice versa.

Example:

Pretty -> pRETTY

Solution:

We are lucky Python has a swapcase Function we can use it directly

def swap_case(s):
    t=.s.swapcase()
    return t

Output:

Have a Nice Day
hAVE A nICE dAY

I am still wondering when this function is useful?

2. String Split and Join

You are given a string. Split the string on a " " (space) delimiter and join using a - hyphen.
Note: A string is a collection of Characters

def split_and_join(line):
    t=line.split(" ")
    t1="-".join(t)
    return t1

split_and_join(i am cool)

#output
i-am-cool

 

3.  Everybody is wonderful!

Suppose we are generating a greeting card with  “Hallo, Firstname Lastname, Du  bist Wunderbar !

def welcome_n(a,b):
    print("Hallo %s %s, Du bist Wunderbar !" %(a, b) )
    
Welcome_n("Nora","N")

# Output

Hallo Nora N, Du bist Wunderbar !

“Wunderbar” is my favorite Deustch word.
Nora’s brother Lucas used to say “Wunderbar, fangya ! Wonderbar” 🙂

Happy Python Learning!!!🐍
