Step 1 ：The table below shows the Consumer Price Index (CPI) for Germany and the Venezuela.

Step 2 ：Data on Consumer Price Index

Step 3 ：$$\text{Unknown environment 'tabular'}$$

Step 4 ：The inflation rate is calculated by the formula: $$\text{Inflation rate}=\frac{\text{CPI in the end year}-\text{CPI in the start year}}{\text{CPI in the start year}}\times 100\mathrm{\%}$$

Step 5 ：In this case, the start year is 2009 and the end year is 2010. We can substitute the CPI values for Germany into the formula to find the inflation rate.

Step 6 ：CPI_2009 = 99

Step 7 ：CPI_2010 = 100

Step 8 ：inflation_rate = 1.0101010101010102

Step 9 ：Final Answer: The inflation rate in Germany between 2009 and 2010 is $\boxed{{\displaystyle 1.01\mathrm{\%}}}$.
