3. Convert a String to Uppercase in Python You can use theupper()function to convert characters in a string to uppercase. Theupper()function returns a new string with all the characters in the original string converted to uppercase. It does not modify the original string. For example, The...
A better approach which can be considered faster but slightly less random way is to use random.sample instead of choosing each letter separately, If n-repetitions are allowed, enlarge your random basis by n times e.g. import random import string char_set = string.ascii_uppercase + ...
# Checking for uppercase letter and # converting to lowercase. elif (a.islower()) == True: count2+= 1 newstring+=(a.upper()) # Checking for whitespace letter and # adding it to the new string as it is. elif (a.isspace()) == True: count3+= 1 newstring+= a print("In origi...
They describe .lower() as converting cased characters to lowercase, where cased characters are "those with general category property being one of “Lu” (Letter, uppercase), “Ll” (Letter, lowercase), or “Lt” (Letter, titlecase)". Same with .upper() and uppercase. With .casefold(),...
def convert_lowercase_to_uppercase(sentence): converted_sentence = sentence.upper() return converted_sentence # 示例输入英文句子 input_sentence = input("请输入一个英文句子:") result = convert_lowercase_to_uppercase(input_sentence) print("转换后的句子:", result) ...
These expressions have the form [f(w) for ...] or [w.f() for ...], where f is a function that operates on a word to compute its length, or to convert it to uppercase. For now, you don’t need to understand the difference between the notations f(w) and w.f(). Instead, ...
ascii_upper_case = string.ascii_uppercase # Output: ABCDEFGHIJKLMNOPQRSTUVWXYZ for one_letter in ascii_upper_case[:5]: # Loop through ABCDE print(ord(one_letter)) Output: # Convert digit characters to their ASCII decimal numbers ascii_digits = string.digits # Output: 0123456789 ...
UpperCaseMixin也适用于Counter。③不要使用pass,最好提供一个文档字符串来满足class语句语法中需要主体的需求。这里是uppermixin.py中的一些 doctests,用于UpperDict:>>> d = UpperDict([('a', 'letter A'), (2, 'digit two')]) >>> list(d.keys()) ['A', 2] >>> d['b'] = 'letter B' ...
You can create new strings using the built-in str() function. However, a more common use case for this function is to convert other data types into strings, which is also a way to create new strings.Consider the following examples:
