Which of the following statements is false.
a. You can import all identifiers defined in a module with a wildcard import of the form from modulename import * b. A wildcard import makes all of the module’s identifiers available for use in your code. c. Importing a module’s identifiers with a wildcard import can lead to subtle errors—it’s considered a dangerous practice that you should avoid. d. The following session is a safe use of a wildcard import: In [1]: e = 'hello' In [2]: from math import * In [3]: e Out[3]: 2.718281828459045 Answer: d. The following session is a safe use of a wildcard import: In [1]: e = 'hello' In [2]: from math import * In [3]: e Out[3]: 2.718281828459045 Actually, this session is a classic example of why you should not use wild-card imports. Initially, we assign the string 'hello' to a variable named e. After executing snippet [2] though, the variable e is replaced, possibly by accident, with the math module’s constant e, representing the mathematical floating-point value e. 4.14 Q2: Which of the following statements is false? a. Sometimes it’s helpful to import a module and use an abbreviation for it to simplify your code. The import statement’s as clause allows you to specify the name used to reference the module’s identifiers. For example, we can import the statistics module and access its mean function as follows: In [1]: import statistics as stats In [2]: grades = [85, 93, 45, 87, 93] In [3]: stats.mean(grades) Out[3]: 80.6 b. import…as is frequently used to import Python libraries with convenient abbreviations, like stats for the statistics module. c. The numpy module is typically imported with import numpy as npy d. Typically, when importing a module, you should use import or import…as statements, then access the module through the module name or the abbrevia-tion following the as keyword, respectively. This ensures that you do not acci-dentally import an identifier that conflicts with one in your code.
