length = len(string)print("The length of the string is:", length)输出结果为：The length of the string is: 13 方法二：使用循环获取字符串的长度 我们也可以使用循环来遍历字符串，并计算字符串的长度。下面是一个示例代码：string = "Hello, world!"count = 0 for char in string:count += 1 pri...
Strings can beconcatenatedto build longer strings using the plus sign and also they can bemultipliedby a number, which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen...
A. len() B. length() C. strlen() D. stringLength() 相关知识点: 试题来源: 解析 A。在 Python 中,获取字符串长度的函数是 len()。length()、strlen()、stringLength()在 Python 中都不是获取字符串长度的函数。反馈 收藏
str = "Tutorials"#iterate through each character of the string # and count them length=((str).join(str)).count(str) + 1 # Print the total number of positions print("The total number of characters in the string: ",length)输出：The total number of characters in the string: 9 好！上面...
string = "Python"length = len(string)print(length) 输出: 6 在上述示例中，我们使用len()函数获取字符串"Python"的长度。3. 判断子字符串是否存在 可以使用in关键字判断一个字符串是否包含指定的子字符串。string = "Python is a powerful programming language."contains = "programming" in stringprint(...
# Define a function named string_length that takes one argument, str1. def string_length(str1): # Initialize a variable called count to 0 to keep track of the string's length. count = 0 # Iterate through each character in the input string str1. for char in str1: # For each ...
length_of_string=32print(''.join(random.choice(string.ascii_letters+string.digits)for_inrange(length_of_string)),end='') 在copyq中,按f6,打开命令面板,新建一个随机数命令,然后选一个有意思的图标 点开右下的显示高级,然后在命令中输入下面的命令,便可调用Python脚本,使用|,可以将输出传递到下一条命...
String Length To get the length of a string, use thelen()function. Example Thelen()function returns the length of a string: a ="Hello, World!" print(len(a)) Try it Yourself » Check String To check if a certain phrase or character is present in a string, we can use the keywordin...
unicode_string="你好,世界"length=sys.getsizeof(unicode_string)-sys.getsizeof("")print("字符串的长度为:",length) 1. 2. 3. 4. 5. 上述代码中,我们导入了sys模块,并定义了一个Unicode字符串unicode_string。然后,我们使用sys.getsizeof()函数获取了字符串的长度,并通过减去空字符串的长度来得到实际...
Python String Length In Python, we use thelen()method to find the length of a string. For example, greet ='Hello'# count length of greet stringprint(len(greet))# Output: 5 Run Code String Membership Test We can test if a substring exists within a string or not, using the keywordin....
