初学者使用Python,但是我想使用一个列表来包含用户在输入中可能给出的多个潜在的字符串响应。
def Front_Door():
print("Welcome to the Party Friend!")
Emotional_state = input("How are You Today? ")
Positive_Emotion = ["good", "fine", "happy"]
我试着使用if语句让python检查我的列表,看看输入中是否包含例如我给出的字符串。
if Posit
执行完我的python文件后,我得到的结果是: R object with classes: ('data.frame',) mapped to:
<DataFrame - Python:0x7f3f3c05a388 / R:0x563006a79ea8>
[DataFrame, DataFrame, DataFrame, DataFrame, ..., DataFrame, DataFrame, DataFrame, DataFrame]
R object with classes: ('data.frame',) mapped to:

我试图‘翻译’(我的意思是python可以理解的语言) '2x^2+3',我想得到'2*x^2 +3‘(这样python就可以理解它了)。
eq = '2x^2+3'
newlist = []
if '^' in eq:
eq = eq.replace('^', '**')
else:
print ''
for x in range (len(eq)):
newlist.append(eq [x])
print newlist
然后我得到了'2',
当我运行pip编译时,生成的文件的一部分如下:
# This file is autogenerated by pip-compile with python 3.8
我认为这是因为我克隆了一个包含setup.py的项目,该项目曾指定Python3.8。但是,我修改了大量代码并删除了setup.py,这样代码中就不再有对Python3.8的引用了,我现在实际上正在使用Python3.9。尽管如此,即使在调用pip-compile之前在同一个shell中激活了Python3.9venv,包含Python3.8的行也会在需求文件中结束。如何将pip编译重新配置为输出3.9?
