Iterate each cell in a specific column in csv by using pandas in Python

Question

I have a CSV file, I want to iterate each row of only one specific column.

Let's say, the column name is "phrase", there are 1000 rows in this column as follows:

ID	phrase
1	apple
2	banana
...	...

How can I iterate each cell in this column?

I have tried to use:

df = pd.read_csv('myfile.csv', usecols=[1])
for row in df:
    print(row)

I only get value of the first row of this column, not iterate each row, as follows:

Current output:
phrase

Desired output:
phrase # with or without this one are all OK
apple
banana

Does anyone know how can I get the desired result? Thanks!
