Number of π bonds and σ bonds in the following structure is 

[Step 1]:
All C-H bonds are single covalent bonds are σ bonds.
[Step 2]:
All C-C single covalent bonds are σ bonds.
[Step 3]:
C=C double covalent bond contain one σ bond and one π bond.
[Step 4]:
Therefore number of C-H  σ bonds = 10
number of  C-C  σ bonds = 7
number of  C=C  σ bonds = 6
number of  C=C  π bonds = 6
