Hướng dẫn python remove every nth character from string - python xóa mọi ký tự thứ n khỏi chuỗi

Tôi hiện đang cố gắng thực hiện thử thách này trong đó nó mang lại cho tôi một chuỗi, chẳng hạn như 'Python' và tôi cần xóa mọi ký tự thứ ba hoặc mọi ký tự mà chỉ số chia hết cho 3. Trong ví dụ này, đầu ra sẽ là ____77. Cho đến nay, tôi có phần word[::3] để tìm mỗi ký tự thứ 3, nhưng làm thế nào tôi có thể lấy từng nhân vật này và loại bỏ chúng khỏi chuỗi?

Mã số

word = str[input[]]
newWord = word[::3]
print[newWord] #for testing

Một chuỗi đầu vào là bất biến, nhưng chuyển đổi nó thành một danh sách và bạn có thể chỉnh sửa nó:

>>> word = list[input[]]  # Read in a word
abcdefghijklmnop
>>> del word[::3]         # delete every third character
>>> ''.join[word]         # join the characters together for the result
'bcefhiklno'

Bắt đầu từ một nhân vật khác:

>>> word = list[input[]]

>>> del word[2::3]
>>> ''.join[word]
'12121212'

Kiểm tra điều này:

>>> word = 'Python For All'
>>> new_word = ''.join[character for index, character in enumerate[word] if index%3 != 0]
>>> new_word
'ytonFo Al'

Đây là câu trả lời của tôi:

s = '0123456'
print s[::3]
# 036

# first way[understandable] create a new str
s_new = ''
for i in xrange[len[s]]:
    if i % 3 != 0:
        s_new += s[i]

print s_new
# 1245

# second way
s_lst = [c if i % 3 else '' for i, c in enumerate[s]]
print s_lst
# ['', '1', '2', '', '4', '5', '']
s_new = ''.join[s_lst]
print s_new
# 1245

# you can put it in single line
s_new = ''.join[[c if i % 3 else '' for i, c in enumerate[s]]]
print s_new
# 1245

# third way
s_idx = filter[lambda x: x[0] % 3, enumerate[s]]
print s_idx
# [[1, '1'], [2, '2'], [4, '4'], [5, '5']]
print ''.join[[x[1] for x in s_idx]]
# 1245

Đưa ra một chuỗi, nhiệm vụ là viết một chương trình Python để thay thế mọi ký tự thứ n trong một chuỗi bằng giá trị đã cho K.

Examples:

Đầu vào: test_str = Hồi GeekSforGeek là tốt nhất cho tất cả các geek, k = ‘$, n = 5test_str = “geeksforgeeks is best for all geeks”, K = ‘$’, N = 5

Đầu ra: Geek $ orge $ ks i $ bes $ cho $ tất cả $ eeks geeks$orge$ks i$ bes$ for$all $eeks

Giải thích: Mỗi ký tự thứ 5 được chuyển đổi thành $. Every 5th character is converted to $.

Đầu vào: test_str = Hồi GeekSforGeek là tốt nhất cho tất cả các geek, k = ‘*, n = 5: test_str = “geeksforgeeks is best for all geeks”, K = ‘*’, N = 5

Đầu ra: Geek*orge*ks i*bes*for*all*eeks: geeks*orge*ks i* bes* for*all *eeks

Giải thích: Mỗi lần xuất hiện thứ 5 được chuyển đổi thành *.Every 5th occurrence is converted to *.

Phương pháp 1: Sử dụng vòng lặp và liệt kê []Using loop and enumerate[]

Trong đó, chúng tôi thực hiện một lần lặp của từng ký tự và kiểm tra xem thứ n của nó bằng cách thực hiện modulo, tức là tìm phần còn lại của N. Nếu xảy ra thứ n của nó, ký tự được thay thế bởi K.
