I have Pandas DataFrame like below, col1 is STRING data type:
col1
-----
"123"
"1111"
"287777"
NaN
"222"
And I need to select only these rows where string in "col1" has 3 characters, so as a result i need something like below:
col1:
-----
"123"
"222"
How can I do that in Python Pandas?
CodePudding user response：
You can use the pandas.Series.str.len function for this task:
df[df['col1'].str.len() == 3]
Output:
col1
0 123
4 222
