Python : AZ 범위를 인쇄하는 방법?

Python : AZ 범위를 인쇄하는 방법?

---

1. 인쇄 : abcdefghijklmn

2. 매초 : acegikm

3. urls {hello.com/, hej.com/, ..., hallo.com/}의 색인에 추가 : hello.com/a hej.com/b ... hallo.com/n

---

>>> import string
>>> string.ascii_lowercase[:14]
'abcdefghijklmn'
>>> string.ascii_lowercase[:14:2]
'acegikm'

URL을 작성하려면 다음과 같이 사용할 수 있습니다.

[i + j for i, j in zip(list_of_urls, string.ascii_lowercase[:14])]

---

이것이 숙제라고 가정하면 ;-)-라이브러리 등을 호출 할 필요가 없습니다. 아마도 다음과 같이 chr / ord와 함께 range ()를 사용할 것으로 예상 할 것입니다.

for i in range(ord('a'), ord('n')+1):
    print chr(i),

나머지는 range ()로 조금 더 연주하십시오.

---

힌트 :

import string
print string.ascii_lowercase

과

for i in xrange(0, 10, 2):
    print i

과

"hello{0}, world!".format('z')

---

for one in range(97,110):
    print chr(one)

원하는 값으로 목록 가져 오기

small_letters = map(chr, range(ord('a'), ord('z')+1))
big_letters = map(chr, range(ord('A'), ord('Z')+1))
digits = map(chr, range(ord('0'), ord('9')+1))

또는

import string
string.letters
string.uppercase
string.digits

이 솔루션은 ASCII 테이블을 사용 합니다 . ord문자에서 ASCII 값을 가져오고 chr그 반대의 경우도 마찬가지입니다.

목록에 대해 알고있는 내용 적용

>>> small_letters = map(chr, range(ord('a'), ord('z')+1))

>>> an = small_letters[0:(ord('n')-ord('a')+1)]
>>> print(" ".join(an))
a b c d e f g h i j k l m n

>>> print(" ".join(small_letters[0::2]))
a c e g i k m o q s u w y

>>> s = small_letters[0:(ord('n')-ord('a')+1):2]
>>> print(" ".join(s))
a c e g i k m

>>> urls = ["hello.com/", "hej.com/", "hallo.com/"]
>>> print([x + y for x, y in zip(urls, an)])
['hello.com/a', 'hej.com/b', 'hallo.com/c']

이 질문에 대한 답은 간단합니다. ABC라는 목록을 다음과 같이 만드십시오.

ABC = ['abcdefghijklmnopqrstuvwxyz']

참조해야 할 때마다 다음을 수행하십시오.

print ABC[0:9] #prints abcdefghij
print ABC       #prints abcdefghijklmnopqrstuvwxyz
for x in range(0,25):
    if x % 2 == 0:
        print ABC[x] #prints acegikmoqsuwy (all odd numbered letters)

Also try this to break ur device :D

##Try this and call it AlphabetSoup.py:

ABC = ['abcdefghijklmnopqrstuvwxyz']


try:
    while True:
        for a in ABC:
            for b in ABC:
                for c in ABC:
                    for d in ABC:
                        for e in ABC:
                            for f in ABC:
                                print a, b, c, d, e, f, '    ',
except KeyboardInterrupt:
    pass

Try:

strng = ""
for i in range(97,123):
    strng = strng + chr(i)
print(strng)

---

This is your 2nd question: string.lowercase[ord('a')-97:ord('n')-97:2] because 97==ord('a') -- if you want to learn a bit you should figure out the rest yourself ;-)

list(string.ascii_lowercase)

['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

---

myList = [chr(chNum) for chNum in list(range(ord('a'),ord('z')+1))]
print(myList)

Output

['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

About gnibbler's answer.

Zip -function, full explanation, returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. [...] construct is called list comprehension, very cool feature!

---

Another way to do it

  import string
  pass

  aalist = list(string.ascii_lowercase)
  aaurls = ['alpha.com','bravo.com','chrly.com','delta.com',]
  iilen  =  aaurls.__len__()
  pass

  ans01 = "".join( (aalist[0:14]) )
  ans02 = "".join( (aalist[0:14:2]) )
  ans03 = "".join( "{vurl}/{vl}\n".format(vl=vjj[1],vurl=aaurls[vjj[0] % iilen]) for vjj in enumerate(aalist[0:14]) )
  pass

  print(ans01)
  print(ans02)
  print(ans03)
  pass

Result

abcdefghijklmn
acegikm
alpha.com/a
bravo.com/b
chrly.com/c
delta.com/d
alpha.com/e
bravo.com/f
chrly.com/g
delta.com/h
alpha.com/i
bravo.com/j
chrly.com/k
delta.com/l
alpha.com/m
bravo.com/n

How this differs from the other replies

• iterate over an arbitrary number of base urls
• cycle through the urls and do not stop until we run out of letters
• use enumerate in conjunction with list comprehension and str.format

I hope this helps:

import string

alphas = list(string.ascii_letters[:26])
for chr in alphas:
 print(chr)
