Answer 1

# Camel word input
CamelStr = input('Enter a string in camel notation: ')
# Create an empty letter list of a word in snake notation
letters=[]
# We iterate through all the letters of the earlier 
# entered word letter by letter
for letter in CamelStr:
# If an uppercase character is encountered, add _
    if letter.isupper():
        letters.append('_')
# Add small letters to the list
    letters.append(letter.lower())
# If the initial character in the list is _ then remove it
if letters[0] == '_':
    letters.pop(0)
# Convert the list to a string and print
snake_str =''.join(letters)
print(snake_str)
