  1. POslicing two lists to have same size using for loop in python
    text
    copied!<p>Hello I want to create two new lists from existing lists using for loop.I know by slicing the lists I can get that result but I have a big list with more than a 1000 entries so slicing by counting the index is not very reliable. I am learning python so there may be other ways I am not aware of so would appreciate if anyone can solve my problem.</p> <p>So I have two lists say :</p> <pre><code> a=np.linspace(1,10,30) b=np.linspcae(0,6,30) a array([ 1. , 1.31034483, 1.62068966, 1.93103448, 2.24137931, 2.55172414, 2.86206897, 3.17241379, 3.48275862, 3.79310345, 4.10344828, 4.4137931 , 4.72413793, 5.03448276, 5.34482759, 5.65517241, 5.96551724, 6.27586207, 6.5862069 , 6.89655172, 7.20689655, 7.51724138, 7.82758621, 8.13793103, 8.44827586, 8.75862069, 9.06896552, 9.37931034, 9.68965517, 10. ]) b array([ 0. , 0.20689655, 0.4137931 , 0.62068966, 0.82758621, 1.03448276, 1.24137931, 1.44827586, 1.65517241, 1.86206897, 2.06896552, 2.27586207, 2.48275862, 2.68965517, 2.89655172, 3.10344828, 3.31034483, 3.51724138, 3.72413793, 3.93103448, 4.13793103, 4.34482759, 4.55172414, 4.75862069, 4.96551724, 5.17241379, 5.37931034, 5.5862069 , 5.79310345, 6. ]) </code></pre> <p>so my code is:</p> <pre><code>for i in a: if i &gt;2.27-1. and i&lt;2.27+1: print i </code></pre> <p>which gives me the elements I want from a.</p> <pre><code>1.31034482759 1.62068965517 1.93103448276 2.24137931034 2.55172413793 2.86206896552 3.1724137931 </code></pre> <p>But I also want the corresponding elements in b. i.e.</p> <pre><code>0.20689655 0.4137931 0.62068966 0.82758621 1.03448276 1.24137931 1.44827586 </code></pre> <p>How do I go from here to get the desired result. </p>
