python單詞首字母大寫

Here, we are implementing a python program to capitalizes the first letter of each word in a string.

在這里，我們正在實現一個python程序來大寫字符串中每個單詞的首字母。

Example:

例：

    Input: "HELLO WORLD!"
Output: "Hello World!"

Method 1: Using title() method

方法1：使用title()方法

# python program to capitalizes the 
# first letter of each word in a string
# function 
def capitalize(text):
return text.title()
# main code 
str1 = "Hello world!"
str2 = "hello world!"
str3 = "HELLO WORLD!"
str4 = "includehelp.com is a tutorials site"
# printing
print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print("str4: ", str4)
print()
print("capitalize(str1): ", capitalize(str1))
print("capitalize(str2): ", capitalize(str2))
print("capitalize(str3): ", capitalize(str3))
print("capitalize(str4): ", capitalize(str4))

Output

輸出量

str1:  Hello world!
str2:  hello world!
str3:  HELLO WORLD!
str4:  includehelp.com is a tutorials site
capitalize(str1):  Hello World!
capitalize(str2):  Hello World!
capitalize(str3):  Hello World!
capitalize(str4):  Includehelp.Com Is A Tutorials Site

Method 2: Using loop, split() method

方法2：使用循環，split()方法

# python program to capitalizes the 
# first letter of each word in a string
# function 
def capitalize(text):
return  ' '.join(word[0].upper() + word[1:] for word in text.split())
# main code 
str1 = "Hello world!"
str2 = "hello world!"
str3 = "HELLO WORLD!"
str4 = "includehelp.com is a tutorials site"
# printing
print("str1: ", str1)
print("str2: ", str2)
print("str3: ", str3)
print("str4: ", str4)
print()
print("capitalize(str1): ", capitalize(str1))
print("capitalize(str2): ", capitalize(str2))
print("capitalize(str3): ", capitalize(str3))
print("capitalize(str4): ", capitalize(str4))

Output

輸出量

str1:  Hello world!
str2:  hello world!
str3:  HELLO WORLD!
str4:  includehelp.com is a tutorials site
capitalize(str1):  Hello World!
capitalize(str2):  Hello World!
capitalize(str3):  HELLO WORLD!
capitalize(str4):  Includehelp.com Is A Tutorials Site
