使用len()函数检查字符串长度 在Python中,我们可以使用内置函数len()来获取字符串的长度。len()函数返回字符串中的字符数,包括空格和标点符号。下面是一个简单的示例: # 定义一个字符串str="Hello, World!"# 使用len()函数获取字符串的长度length=len(str)print("字符串的长度为:",length) 1. 2. 3. 4....
The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects ...

Variable 'a' is not a type of string. Variable 'b' is not a type of string. Variable 'c' is a type of string. Variable 'd' is a type of string. Variable 'e' is a type of string. To understand the above programs, you should have the basic knowledge of the following Python top...
print('Input is not a String') else: print(len(strInput)) length_of_string(str1) length_of_string(str2) Output: Input is not a String 9 You can also use type() function rather than isInstance here. That’s all about how to check if variable is String in Python Was this post ...

To check if a string is empty or whitespace using thelen()function in Python, we will use the following steps. First, we will find the length of the input string using thelen()function. We will store the length in a variablestr_len. ...
