Create a string of all alphabetical characters usingstring.ascii_lowercaseandstring.ascii_uppercase. Usetranslate()withmaketrans()to remove all alphabetical characters fromstring. Convertcleaned_stringto an integer withint(). import string strObj = "abc345xyz" alphabet = strObj.ascii_lowercase + str...
import random alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()' char = random.choice(alphabet) print(char) (3) 生成随机字符串 生成指定数量的随机字符串 import random alphabet = 'abcdefghijklmnopqrstuvwxyz!@#$%^&*()' characters = random.sample(alphabet, 5) print(characters) 从a-zA-Z0-...
UTF-8 The range of integers used to code the abstract characters is called the codespace. A particular integer in this set is called a code point. When an abstract character is mapped or assigned to a particular code point in the codespace, it is then referred to as an encoded character...
Authors whose names are not based on the Latin alphabet (latin-1, ISO/IEC 8859-1 character set) MUST provide a transliteration of their names in this character set. Python的标准库遵循了以上规范,建议开源项目都效仿这种标准。 import 推荐导入不同的库时分行导入: # Correct: # 推荐的写法: import...
base64.b32decode() now raises a binascii.Error when the input string contains non-b32-alphabet characters, instead of a TypeError. This particular TypeError was missed when the other TypeErrors were converted. (Contributed by Serhiy Storchaka in bpo-18011.) Note: this change was also inadverte...
The Caesar cipher works by taking a letter to be encrypted and shifting it a certain number of positions to the left or right in the alphabet. Whichever letter is in that position is used as the encrypted character. This same shift value is applied to all characters in the string....

在Python程序中生成验证码并不算特别复杂,但需要三方库Pillow的支持(PIL的分支),因为要对验证码图片进行旋转、扭曲、拉伸以及加入干扰信息来防范那些用OCR(光学文字识别)破解验证码的程序。 下面的代码封装了生成验证码图片的功能,大家可以直接用这些代码来生成图片验证码,不要“重复发明轮子”。 代码语言:javascript 代...
0 through 31 Control/non-printable characters 32 through 64 Punctuation, symbols, numbers, and space 65 through 90 Uppercase English alphabet letters 91 through 96 Additional graphemes, such as [ and \ 97 through 122 Lowercase English alphabet letters 123 through 126 Additional graphemes, such as...
We will not specify thetostrbut we will use thedeletestrparameter to delete all of the punctuation. We will even let Python tell us the list of characters that it considers “punctuation”: >>> import string >>> string.punctuation
