My question is: is there any way i can somehow use all the returned capital letter indices and replace them ALL with an underscore? I wished to take the returned values from the uppercase_finder function and insert an underscore in front of those capitalized letters. However, when I run the program, I only get the first capital letter of input with an underscore. Can I somehow iterate all the returned uppercase indices into the part where I insert underscores?
def main():
first_input = input("input here: ")
uppercase_indice = uppercase_finder(first_input)
new_case = first_input[:uppercase_indice] + "_" + first_input[uppercase_indice:]
new_case = new_case.lower()
print(new_case)
def uppercase_finder(x):
for i in range(len(x)):
if x[i].isupper():
return i
main()
Okay so based on the assumption that the overall goal is to print out the string inputted all lowercase and an underscore appended to each letter that was uppercase.
You could iterate through each letter in the string without focusing on the indices at all. Something like:
def main():
first_input = input("input here: ")
updated_input = ""
for letter in first_input:
if(letter.isupper()):
updated_input += "_" + letter.lower()
else:
updated_input += letter
print(updated_input)
Output:
input here: HeLLo
_he_l_lo
Generally though if you want to stick with the uppercase_finder function, the return statement in the loop stops the loop the moment any letter that is uppercase is found. In order to get all of the indices of each letter that is uppercase you would need something like this:
def uppercase_finder(x):
list_of_indices = []
for i in range(len(x)):
if x[i].isupper():
list_of_indices.append(i)
return list_of_indices
Then in the main function you can iterate across the list:
for index in uppercase_indice:
# Make string manipulations for each index
