将Python中的每个单词的首字母大写

Question

how do you capitalize the first letter of each word in the column? I am using python pandas by the way. For example,

         Column1
         The apple
         the Pear
         Green tea

My desire result will be:

         Column1
         The Apple
         The Pear
         Green Tea

Answer 1

You can use str.title :

print (df.Column1.str.title())
0    The Apple
1     The Pear
2    Green Tea
Name: Column1, dtype: object

Another very similar method is str.capitalize , but it uppercases only first letters:

print (df.Column1.str.capitalize())
0    The apple
1     The pear
2    Green tea
Name: Column1, dtype: object
