In this article, I will explain the Python stringcapitalize()method and slicing technique how we can capitalize the first letter of a string, and also explain using several methods likecapitalize(),title(),upper(),split(), andstring.capwords()functions how we can capitalize the first letter o...
Capitalizes first letter of each word in a string using loop, split() method # python program to capitalizes the# first letter of each word in a string# functiondefcapitalize(text):return' '.join(word[0].upper()+word[1:]forwordintext.split())# main codestr1="Hello world!"str2="h...
def decapitalize_first_letter(s, upper_rest=False): # Join the first letter in lowercase with the rest of the string, optionally capitalizing the rest return ''.join([s[:1].lower(), (s[1:].upper() if upper_rest else s[1:])]) # Test the function with different input strings and...
In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
To convert the first letter/character of a string to a lowercase in Python, you can use the lower() method and concatenate it with the rest of the string.
deflowercase_first_letter(string):returnstring[0].lower()+string[1:]strings=["Hello","World","Python"]lowercased_strings=[lowercase_first_letter(s)forsinstrings]print(lowercased_strings)# 输出:['hello', 'world', 'python'] 1. 2.
import string # Convert uppercase characters to their ASCII decimal numbers ascii_upper_case = string.ascii_uppercase # Output: ABCDEFGHIJKLMNOPQRSTUVWXYZ for one_letter in ascii_upper_case[:5]: # Loop through ABCDE print(ord(one_letter)) Output: 代码语言:javascript 代码运行次数:0 运行 AI...
The first letter of 'hello' is 'h'. (7)数字的处理 ① 保留小数位数 str1 = "π is {:.2f}.".format(3.1415926) #保留两位小数 print(str1) 执行以上代码,输出结果为: π is 3.14. ② 给数字加千位符 str1 = "{:,}".format(100000000) print(str1) 执行以上代码,输出结果为: 100,000,000...

This example demonstrates how to use the any and isalpha functions to check if a character string contains a letter from the alphabet. Let’s check our first character string my_string1: print(any(c.isalpha()forcinmy_string1))# Check if letters are contained in string# True ...
