I am a beginner and I am having a problem returning a value in python. The Question is as follows: Write a function called get_capitals. get_capitals should accept one parameter, a string. It should return a string containing only the capital letters from the original string: no lower-case letters, numbers, punctuation marks, or spaces. In short, the function should return the string which will only contain capital letters. My code is:
def get_capitals(a_string):
for x in a_string:
ordinal_number=ord(x)
if ordinal_number>=60 and ordinal_number<=90:
print(x,end=""))
# print(ordinal_number)
Using function call
print(get_capitals("CS1301"))
call with the above call the above code i am able to print the result i desire but it returns None. which I am trying to avoid. Can someone tell me how can I return a result of the print function?
As far as my understanding goes, You need a program that only returns letters that is in Capital in a String. I developed a program, have a look.
My Code:
def get_capitals (a_string):
upper_case_chars = ""
for i in a_string:
if i.isupper():
upper_case_chars = upper_case_chars + i
return upper_case_chars
print (get_capitals("CSFF57456"))
Use list comprehension and join
def get_capitals(a_string):
return ''.join(c for c in a_string if c.isupper())
