Advanced pandas—Going Beyond the Basics

Which string methods in `pandas` is used to extract a part of a string based on its position?

Which string methods in <code>pandas</code> is used to extract a part of a string based on its position?

**(True or False)** The `partition()` method is similar to `split()` except that it splits the string at the last occurrence of the separator. 

(True or False) The <code>partition()</code> method is similar to <code>split()</code> except that it splits the string at the last occurrence of the separator.

The `join` parameter of the `cat()` string method allows us to align the indexes before concatenation.

The pattern matching in the `match()` method is case-sensitive because the default value for the `case` parameter is `True`. 

The `pat` separator parameter of the `split()` method only takes in string values and does not accept regular expressions.

The `match()` method makes it such that a match can occur at any position within the string.

**(Select all that apply.)** Which  statements are *true*? 

(Select all that apply.) Which statements are true?

The `extract()` and `extractall()` methods work on both string and regex patterns.

Through this line of code: `df['email'].str.replace('.com', '.org', regex=False, case=True)`, the email address ending with the string `.com` will have these suffixes replaced with `.org` in a case-sensitive manner.

When we set the `expand` parameter in the `extract()` string method as `True`, the extracted substring output will be in the form of a DataFrame column.

The `find()` method is used to get the first matching substring from a string column based on a regex pattern.

**(Select all that apply.)** Which statements are *true*? 

(Select all that apply.) Which statements are true?

**(True or False)** The `ljust()` method pads the left side of string values with an arbitrary character defined in the `fillchar` parameter. It is equivalent to setting `side='left'` in the `pad()` method.

(True or False) The <code>ljust()</code> method pads the left side of string values with an arbitrary character defined in the <code>fillchar</code> parameter. It is equivalent to setting <code>side='left'</code> in the <code>pad()</code> method.
