title: For loop in python 3 (multiple Iteration)
body: <p>I read a csv file named df, which has 4 columns(id, skill,..) and 30 rows, I want the program to check each id and if the id is "A035755" then print its related skill (j). I wrote the following program it almost works but the problem is it iterates more than once so instead of 30 results I have more than 100!<br>
  I think my indexing might be the problem but not sure how to fix it.</p>
  
  <p>Thanks J</p>
  
  <pre><code>df=pd.read_csv('location')
  for i in df.id[0:len(df)]:  #id is one of the columns
      for j in df.skill:       #skill another column
          if i == "A035755":
              print(j)
          else:
              print("Not Found")
  </code></pre>
