So many weird syntax errors

I’m working on deploying something and it’s been going fine, but then I started getting all these weird syntax errors. Two examples:
A)
This code works totally fine and displays the chart:

ward_housing_cost = alt.Chart(df_ward).mark_bar().encode(
 alt.X('Ward:N', axis=alt.Axis(format='d')),
 alt.Y('avg_housing_cost_ward:Q', title = 'rating of housing cost', 
 scale=alt.Scale(domain=(0, 5))
 ).properties(title = 'Rating of housing cost by ward')
st.altair_chart(ward_housing_cost)

…but this one gets the syntax error:

ward_streets_sidewalks = alt.Chart(df_ward).mark_bar().encode(
 alt.X('Ward:N'),
 alt.Y('avg_streets_sidewalks_ward:Q', title = 'rating of maintenance of 
 streets/sidewalks')
 ).properties(title = 'Rating of maintenance of streets/sidewalks by ward')
st.altair_chart(ward_streets_sidewalks)

here is what the error looks like:

File "/app/shs2021/streamlit_app.py", line 90
  ward_streets_sidewalks = alt.Chart(df_ward).mark_bar().encode(
                       ^
SyntaxError: invalid syntax

I have tried everything I can think of including rewriting the thing from scratch, renaming the chart, etc.

B) So then I took out all the ward charts to work on another part and the whole sidebar, which hadn’t touched, broke. Now I’m getting a brand-new syntax error on this, which - again - I have not touched:

navigation = st.sidebar.radio("Explore the data by:", ('Introduction', 'Overall trends', 'Age', 'Gender', 'Income', 'Race', 'Ward')) 

this is what the error looks like:

File "/app/shs2021/streamlit_app.py", line 96
  navigation = st.sidebar.radio("Explore the data by:", ('Introduction', 'Overall trends', 'Age', 'Gender', 'Income', 'Race', 'Ward'))
           ^
SyntaxError: invalid syntax

What is happening??

Syntax errors should be pretty quick to find, but not from this code snippet.
Can you share a github link?

I found the syntax error. It was actually in the code block ABOVE where the error said it was.
