'''Ex. 1: Create a program to store the given variables name and age'''

x = input('Give me your name please:')
y = input('now, give me your nationatily: ')

print('Nice to meet you,', x, 'is always good to meet a ', y)


#%%

'''Ex. 2: From the previous exercise, show the type of each variable…'''

type(x)
type(y)


#%%
'''Ex. 3: …and print the following sentence'''
# print the output




#%%
'''Ex. 4: Create a program to receive a year and return the age'''

x = int(input('Could you please provide me the year you were born?: '))

y = 2024 - x
print('Based on the year you were born you have', y, 'years old')



#%%
'''
Ex. 5: Create a program that given 1 integer and 1 float returns:
   - The modulus as integer
   - The floor division
   - The cube of the integer number
'''
v = 4
l = 8


h = int(input('Give me a number: '))
v = int(input('and another one: '))
print('Based on both number here is the floor division: ',h // v, 'and the cube of the first number: ', h*v)








#%%
'''
Ex. 6: Create two variables:
    empty_string variable with no text
    sentence = "Python is awesome"
    And calculate:
    - The length of each variable.
    - Write in uppercase the text from sentence
    - Replace "Python" with "coding"
'''

e_st =''
sentence = 'Python is awesome'
len(e_st)
len(sentence)

print(sentence.lower())
print(sentence.upper())
sentence.replace('Python', 'coding')




#%%
'''
Ex. 7: Create a program to receive a sentence and return the text in lowercase and without spaces
'''
sentence = input('Give me a sentence: ').strip()

# Initialize an empty string to store the modified sentence
modified_sentence = ''


for char in sentence:
    # Check if the character is not a space
    if char != ' ':
        # Convert the character to lowercase and add it to the modified sentence
        modified_sentence += char.lower()

# Print the modified sentence
print("Modified Sentence (lowercase and without spaces):", modified_sentence)
        








#%%
'''
Ex. 8: Create the variable class_signature = 'Python exercises'.
   - Get the first character
   - Get the second to last character
   - Get the fifth character
   - Get the twentieth character

'''

class_signature = 'Python exercises'

class_signature[0]

class_signature[-2]

class_signature[4]

class_signature[20]



#%%
'''
Ex. 9: Create a program to slice both words from the previous variable class into 2 different variables
'''

class_signature ='Python exercises'

word1 = ''
word2 = ''

first_word_done = False

for char in class_signature:
    if char != '' and not first_word_done:
        word1 += char
    elif char=='':
        first_word_done = True
    elif first_word_done:
        word2 += char

print('first word', word1)
print('second word', word2)




#%%
'''
Ex. 10: Create a variable with the following text: “slicing not grouping” and extract the word “sing” from it with one code line. 
'''

text = 'slicing not grouping'

text[5:9]




#%%
'''
Ex. 11: Create a program that count the number of times the letter “a” appear in a sentence ignoring upper or lowercases
'''
gili = 'I love to go to the park on saturdays and sundays'

gili_2 = gili.count('a')
print(gili_2)


#%%
'''
Ex. 12: Create a program that given 2 strings, return a new variable created with the first, middle and last letter of each string.
'''

# Define las cadenas de texto
first_str = 'Hello'
second_str = 'I love you'

# Obtiene la primera, la letra del medio y la última letra de la primera cadena
first_middle_last_first_str = first_str[0] + first_str[len(first_str)//2] + first_str[-1]

# Obtiene la primera, la letra del medio y la última letra de la segunda cadena
first_middle_last_second_str = second_str[0] + second_str[len(second_str)//2] + second_str[-1]

# Imprime la nueva variable creada para la primera cadena
print("Nueva variable creada para la primera cadena:", first_middle_last_first_str)

# Imprime la nueva variable creada para la segunda cadena
print("Nueva variable creada para la segunda cadena:", first_middle_last_second_str)
