A seeker after truth
P) Given a DNA strand, return its RNA complement (per RNA transcription). Both DNA and RNA strands are a sequence of nucleotides. The four nucleotides found in DNA are adenine (**A**), cytosine (**C**), guanine (**G**) and thymine (**T**). The four nucleotides found in RNA are adenine (**A**), cytosine (**C**), guanine (**G**) and uracil (**U**). Given a DNA strand, its transcribed RNA strand is..
P) Determine if a sentence is a pangram. A pangram (Greek: παν γράμμα, pan gramma, "every letter") is a sentence using every letter of the alphabet at least once. The best known English pangram is: > The quick brown fox jumps over the lazy dog. The alphabet used consists of ASCII letters `a` to `z`, inclusive, and is case insensitive. Input will not contain non-ASCII symbols. mysol) def is_pangr..
P) Given a year, report if it is a leap year. The tricky thing here is that a leap year in the Gregorian calendar occurs: ```text on every year that is evenly divisible by 4 except every year that is evenly divisible by 100 unless the year is also evenly divisible by 400 ``` For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap year, but 2000 is. mysol) def leap_year(year): if ye..
sol1) 참고 - https://itholic.github.io/python-reverse-string/ def reverse(text): return text[::-1] sol2) s = 'abcde' s_list = list(s) s_list.reverse()# reverse는 list에만 사용 가능 print(''.join(s_list)) sol3) print(''.join(reversed(s))) #reversed는 문자열에 바로 적용이 가능하다. #join 함수는 리스트와 문자열에 모두 사용 가능(iterable한 것)
