方法一：使用字符串的内置方法 Python中的字符串有一个内置的方法lower()和upper()，分别用于将字符串转换为小写和大写形式。代码如下：# 定义一个字符串string = 'Hello, World!'print('源字符串为：', string)# 将字符串转换为小写形式lowercase_string = string.lower()print('字符串转换为小写：')print(l...
"lowercase_string = string.lower()print(lowercase_string) # 输出：hello, world!uppercase_string = string.upper()print(uppercase_string) # 输出：HELLO, WORLD!capitalized_string = string.capitalize()print(capitalized_string) # 输出：Hello, world!# 字符串的填充和对齐left_aligned_string = str...
str.upper() 函数用于将字符串转换为大写形式。它接受一个字符串作为参数，并返回一个新的字符串，其中所有字符都被转换为大写。以下是一个示例：python复制代码string = "Hello, world!" uppercase = string.upper()print(uppercase) # 输出：HELLO, WORLD!str.lower() 函数 str.lower() 函数用于将字符串...
1. len(): 返回字符串的长度。string = "Hello, World!"length = len(string)print(length) # 输出 13 2. upper(): 将字符串中的所有字符转换为大写。uppercase_string = string.upper()print(uppercase_string) # 输出 "HELLO, WORLD!"3. lower(): 将字符串中的所有字符转换为小写。lowercase_strin...
A string containing all the characters that are considered uppercase letters. On most systems this is the string 'ABCDEFGHIJKLMNOPQRSTUVWX YZ'. Do not change its definition — the effect on the routines lower() and swapcase() is undefined. The specific value is locale-dependent, and will be ...

firstString = "der Fluß" secondString = "der Fluss" # ß is equivalent to ss if firstString.casefold() == secondString.casefold(): print('The strings are equal.') else: print('The strings are not equal.') 在上面的示例中,我应该使用: lower() # the result is not equal which...
print("Lower Case String:",lower_case_string) 代码解析: original_string.upper():调用upper()方法将字符串original_string中的所有字符转换为大写,并将结果存储在upper_case_string中。 original_string.lower():调用lower()方法将字符串original_string中的所有字符转换为小写,并将结果存储在lower_case_string中...
