Python Decisions¶

One way decision¶

In [1]:

x = 25
if x > 10:
    print('big')
    print('it is big')
print('done')

big
it is big
done

In [2]:

x = 2
if x > 10:
    print('big')
    print('it is big')
print('done')

done

Two ways decision¶

In [3]:

x = 25
if x > 10:
    print('big')
    print('it is big')
else:  # x <=10
    print('small')
    print('it is small')
print('done')

big
it is big
done

In [4]:

x = 7
if x > 10:
    print('big')
    print('it is big')
else:  # x <=10
    print('small')
    print('it is small')
print('done')

small
it is small
done

Multi-ways decisions¶

In [5]:

x = 15
if x > 10:
    print('big')
    print('it is big number')
elif x < 5:  # x <= 10
    print('small')
    print('it is small')
else:
    print('between 5 and 10')
print('done')

big
it is big number
done

In [6]:

x = 7
if x > 10:
    print('big')
    print('it is big number')
elif x < 5:  # x <= 10
    print('small')
    print('it is small')
else:
    print('between 5 and 10')
print('done')

between 5 and 10
done

In [7]:

x = 3
if x > 10:
    print('big')
    print('it is big number')
elif x < 5:  # x <= 10
    print('small')
    print('it is small')
else:
    print('between 5 and 10')
print('done')

small
it is small
done
