balanced emoticons: a playful critical code study¶

this is written for the doggies and kitties in the anthropo-sphere
methods implemented were referred with caution to the following:
https://www.geeksforgeeks.org/python-program-check-string-palindrome-not/ more cat emoticons: https://www.copyandpastesymbols.net/emoticon/cat-emoticons.html

In [21]:

# palindrome method 
# slice the string backwards 

def isBalanced(s):
    if s == s[::-1]:
        print("{} is a balanced emoticon!".format(s))
    else:
        print("{} is not a balanced emoticon, try another one?".format(s))

# try a simple emoticon
suprised_f = "0_0"
isBalanced(suprised_f)

0_0 is a balanced emoticon!

In [22]:

cat_hearty = "(*♥^•ﻌ•^♥*)"
isBalanced(cat_hearty)

(*♥^•ﻌ•^♥*) is not a balanced emoticon, try another one?

In [23]:

#strip the opening brackets and closing brackets 
s_cat_hearty = cat_hearty.strip("()")
isBalanced(s_cat_hearty)

*♥^•ﻌ•^♥* is a balanced emoticon!

In [24]:

#update the isBalanced method 
def isBalanced(s):
    if s == s[::-1]:
        print("{} is a balanced emoticon!".format(s))
    else:
        s_strip = s.strip("()")
        if s_strip == s_strip[::-1]:
            print("{} is a balanced emoticon!".format(s))
        else:
            print("{} is not a balanced emoticon, try another one?".format(s))

In [25]:

#try with the updated method 
isBalanced(cat_hearty)

(*♥^•ﻌ•^♥*) is a balanced emoticon!

In [27]:

# try a list of kitty emoji strings
c_strings_l = ["ლ(●ↀωↀ●)ლ","(ﾟ∀ﾟ)","(=^･ω･^=)","(^・x・^)"]
for string in c_strings_l:
    isBalanced(string)
    print()
    

ლ(●ↀωↀ●)ლ is not a balanced emoticon, try another one?

(ﾟ∀ﾟ) is a balanced emoticon!

(=^･ω･^=) is a balanced emoticon!

(^・x・^) is a balanced emoticon!

In [28]:

d_strings_l = ["▼・ᴥ・▼","U・ﻌ・U"," υ´• ﻌ •`υ","ᐡ ・ ﻌ ・ ᐡ"]
for string in d_strings_l:
    isBalanced(string)
    print()

▼・ᴥ・▼ is a balanced emoticon!

U・ﻌ・U is a balanced emoticon!

 υ´• ﻌ •`υ is not a balanced emoticon, try another one?

ᐡ ・ ﻌ ・ ᐡ is a balanced emoticon!

In [29]:

#why would it not be? 
wide_eyes = "ლ(●ↀωↀ●)ლ"
r_wide_eyes = wide_eyes[::-1]
s_r_wide_eyes = r_wide_eyes.strip("()")
print(s_r_wide_eyes)

ლ)●ↀωↀ●(ლ

in the kitty emoji, the strip method won't work now since it only applies to stripping away leading or trailing chars. therefore the method is buggy, as the pair of brackets are not matching. similarily, in the doggie emoji, the pair of ticks that make up the eyebrows are not assigned as matching.

# bonus program
# printing emoticon trees
# the program will fail 

#  *******************************
#  * run a half loop comparison  *                  
#  *******************************

def isPalindrome(str):
 
    # Run loop from 0 to len/2
    for i in range(0, int(len(str)/2)):
        if str[i] != str[len(str)-i-1]:
            return False
    return True
 
# main function
s = " υ´• ﻌ •`υ"
ans = isPalindrome(s)
 
if (ans):
    print("Half loop comparison says passing test")
else:
    print("Half loop comparison says failing test")
    
#  *******************************
#  * move emoticon to a new var  *

# Python program to check

# or not

x = "υ´• ﻌ •`υ"

w = ""
z = ""
y = ""

print("it's going to print half a doggie tree watch out")
for i in x:
    w = i + w
    print(w)

Half loop comparison says failing test
it's going to print half a doggie tree watch out
υ
´υ
•´υ
 •´υ
ﻌ •´υ
 ﻌ •´υ
• ﻌ •´υ
`• ﻌ •´υ
υ`• ﻌ •´υ

now the eyebrows are flipped and doggie's mood changed, the ticks didn't match the original and it failed the test.

    counter = counter - 1
