print(f"Pi rounded to 2 decimal places: {pi:.2f}") 四、其他格式化方式 百分号格式化:这是Python中最古老的字符串格式化方法,类似于C语言的printf。使用%作为占位符。 name = "Alice" age = 30 print("Name: %s, Age: %d" % (name, age)) 模板字符串:通过string.Template类实现字符串格式化,适用于...
Example 2: C++ More examples on printf() #include <cstdio> int main() { char ch = 'a'; float a = 5.0, b = 3.0; int num = 10; // set precision to 3 decimal places printf("%.3f / %.3f = %.3f \n", a, b, a / b); // set width to 5 digits with * printf("Set...
This example uses format specifiers: %d for integers, %.2f for floats with 2 decimal places, and %c for characters. Each specifier matches the corresponding variable type. The printf function replaces specifiers with variable values in order. Format specifiers ensure proper data representation in ...
4. How would you print a floating-point number with two decimal places using 'printf'? A. %.2f B. %f2 C. %2f D. %.f2 Show Answer 5. Which command allows you to see the version of 'printf' implemented? A. printf --version B. printf -V C. printf -v D. printf ...
Since%fis used for floats, we can use it to printdoubles. However, by adding a.n, wherenis the number of decimal places, we can define custom precision. Running this code yields: a =35.56b =40.1245 Format Padding We can also add padding, including the passed String: ...
